Hi Gimpy. Hope you feel better soon. I think Laura and RedFox gave some good feedback. Psyche will be able to add more. Hopefully that should take care of the immediate/short term problem.
I've fallen behind in keeping up with the diet and health threads a bit, but you probably keep up pretty well, so there's lots of data for you, and the sharing of experiences by members is always a great help. Like Laura and the Chateau team have so much varied experience with varied problems that they've narrowed down what works for whom in what circumstance, etc. So utilize these resources all you can.
For a longer term option, consider reading Hulda Clark's books. She has some great helpful info on many things including liver/bile duct/gallstone problems. A brief summary: she says that gallstones actually form in the liver bile ducts -- thousands of them!! -- and not in the gallbladder She says over the years of testing patients as a naturopath, she never found anyone who did NOT have gallstones, no matter how young or old. The older you are, the more you'll tend to have -- up to 3000 or more. She has a liver cleanse program that flushes out hundreds of stones each time you do it. BUT it MUST be done after killing any possible parasites in the liver. She says you may have the worst night of your life and get few if any stones out if you try to cleanse your liver with live parasites in them.
So, you'd have to do an herbal parasite program and/or zap. You can just use the zapper because the current reaches well into the liver and will kill any parasites. She does also recommend to do some kidney cleanses and have any dental work needed done, particularly removing amalgams and other heavy metals from the mouth for best results, but it's not ABSOLUTELY necessary. She just says it's better to have well functioning kidneys and urinary system to efficiently remove any undesirable substances incidentally absorbed from the intestines as the bile is being excreted and not put a heavy load with a toxic mouth and burden the liver immediately after cleansing.
The basic recipe / program is: (AFTER KILLING PARASITES) the day you will do the liver cleanse, you eat a non-fat breakfast and lunch, e.g. fruits, steamed veggies, non-gluten cereal etc (no butter or oils) this allows the bile to build up and develop pressure to push out more stones. You don't eat anything or drink after 2PM or you could feel quite ill. You need about two largish pink grapefruits -- enough to make about 3/4 of a cup of juice, 1/2 cup olive oil, and 4 tablespoons of Epsom salts. Around 2PM mix 4 tbs. of Epsom salts in 3 cups of water in a jar. This makes 4 servings of 3/4 cup each. Put it in the fridge to get cold for taste and convenience (unless you prefer to drink it at room temperature).
At 6PM drink the one serving (3/4 cup) of Epsom salts. You can add 1/8 tsp vitamin C powder to improve taste. You may also drink a mouthful or two of water afterwards or rinse your mouth. If you refrigerate the grapefruit and/or olive oil get them out to warm up. At 8PM drink another 3/4 cup of Epsom salts. Get any bedtime chores done as the timing is critical for success (don't be more than 5 to 10 minutes late). Between 9:30 and 9:45PM pour 1/2 cup (measured) olive oil into a pint jar with lid. Squeeze the grapefruit by hand to get 3/4 (measuring) cup (you may add some lemonade to top it up). You can remove any pulp with a fork or I squeeze it through a strainer. Add it to the olive oil and close the lid tightly. Shake hard until watery (only fresh squeezed grapefruit juice does this). Visit the bathroom one or more times as needed.
At 10PM drink the olive oil-grapefruit juice mixture. You can use a large straw to help drink it. She says to take 4 L-Ornithine (amino acid) capsules to be sure you can sleep (8 if you already suffer from insomnia). Or you can take whatever you may be taking for good night sleep that has work for you (GABA, 5-HTP, melatonin, etc. at the right dosages and time for best night sleep). Drink it down within 5 minutes (15 min. max for very old or weak people). Lie down IMMEDIATELY. The sooner, the more stones you'll get out. Be ready for bed ahead of time. Lie on your back with your head up high on a pillow. Try to think about what's happening in the liver. Keep as perfectly still as possible for at least 20 minutes. You may feel a train of stones traveling along the bile ducts like marbles. There's no pain or discomfort because the bile ducts are open from the Epsom salts. Go to sleep, as you may fail to get stones out if you don't.
Next morning, upon waking, take your 3rd dose of 3/4 cup Epsom salts. If you have indigestion or nausea, wait until it's gone before drinking the Epsom salts. You may go back to bed. Don't drink this before 6AM. Two hours later, take your 4th and last dose of Epsom salts. You may go back to bed. After 2 more hours, you may eat. Start out with fruit juice. Half hour later eat fruit. One hour later you may eat regular food but keep it light. By supper you should feel recovered.
Expect diarrhea in the morning lasting at least half the day. It will be mainly liquid, could be clear water with gallstones. The stones will float and though there may be different colors (tan, red, etc) look for the pea green ones as these are surely gallstones coated with bile. You can use a flashlight if need be and count them. You may get 200 to 300 on a good cleanse. There may be white and tan "chaff" too floating which is cholesterol crystals.
I've done this several time over the last 10 to 15 years, as well as my family members and several friends. She says that cleansing the liver bile ducts is one of the most powerful procedures to improve health. It greatly improves digestion, immune system, most allergies should clear up, arthritis, bursitis, joint pains, upper back pains all clear up. And after you get out 2000 or so they tend to clear up permanently. You can do the liver cleanse with 2 to 3 week breaks in between until nothing else comes out. This gives time to recover. You may feel tired the next day or two after a cleanse. As the bile ducts are cleared you produce more bile, the right amount. When the ducts are choked up with stones, not only does not enough bile get pumped into the intestines, your body start producing less bile to compensate for the backed up tubing. This obviously effects digestion of fats (and protein if memory serves).
By the way Gimpy, as I've written before, my mother was diagnosed with having MS or MS like symptoms in 1996 -- couldn't get a definite answer. But she was deteriorating quickly within months of the symptoms starting. She had very poor control over one leg, etc. She zapped with the first zapper I built and did Hulda Clarks herbal parasite program -- black walnut hull, wormwood (Artemisia), and cloves -- after I got and read The Cure for All Diseases and decided to try her recommendations. And in a couple of weeks whatever it was stopped, reversed and disappeared. Given, it was quite early in the disease process, but my mother didn't do anything else advised in the book for MS and did her first liver cleanse several years later, but remained on the maintenance parasite program (once a week) and zapped 1 or 2 times a week. She did have other health problems later on but she had bad diet, habits, high stress, has taken lots of prescription drugs, etc. Anyway, the MS-like thing that was progressing at an alarming rate, did stop and reverse quickly.
I gotta go now, but I'll also post an herbal recipe for general liver function support later.
I've not found much online on how to deal with a sluggish or congested liver, does anyone have any thoughts on what else I can do? 
If its processed, I don't eat it...that goes pretty much for everything from crackers to coke. Sometimes before we go out to eat I'll have a meal at home and then have a salad or steamed veggies, or we go somewhere I can have meat and steamed veggies.
