I should share my experience if it can perhaps help anyone.
I have been using Lugol to treat an esophageal/tongue candida infection which after very long exposure I suspect spread to other systems, blood at the very least, and wrecked inflammatory havoc on my system and my mind.
At first I went with about 50 mg a day and after a while I had a pretty nasty herx episode with cold, rashes, tremors and acne. Kinda stopped for a couple weeks there. Then I realized this isn't working, I'm gonna have to up the dosage. So, I started with 200 mg a day with salt water 1 tsp split into two to three times a day. I immediately felt better. That was about a month and a half ago. Right now, I'm on 600 mg of Iodine a day and I feel better than I have in a long while. Don't plan to go more than about 800 orally. A LOT more will, energy, mental sharpness and quite a bit more productive. The health problems I've had caused a slip in uni as well so I have to deal with that and physical and mental health this semester which isn't easy, but there is hope. That's what drives me right now. A couple of weeks ago I also realized that I need to start applying it topically to my tongue which makes total sense since it is essentially a skin infection, mucose skin sure but skin. That has proved very effective in treating that local infection. The infection is noticeably weaker now than it was, it is still there, but it is weakening. I shouldn't really expect it to go away quickly considering how long I had it anyway - this is gonna be a long battle. Also to mention, on these high dosages no serious herx reactions, a couple of acne here and there and maybe a lymph node expanding but that goes down after a while.
Right now on iodine, vitamin c, milk thistle, turmeric, osteobiflex and frankincense which are for my osteoarthritis which has btw also improved under high dosages of iodine. Wouldn't be surprised if the osteoarthritis was casued by inflammation from candida. Also, plan to start using iodine on moles that have been scaring me. And almost forgot, I'm on the ketogenic diet for a about two months now which I suspect helped as well with the problems, plan to start making fat bombs soon when I get my stevia from iHerb. Right now, my diet is based on eggs, bacon, raw bacon cuts and lard. Gonna have to start meditating too to help with my psychological problems. I also have to repair my sleep cycle, and a step towards that was that I put trash bags on my window because of the light but I still cheat with a light that turns of after 20 minutes, gonna stop doing that, but been scared of the dark since I was a kid.
Have a pretty large order of additional supplements I found on this topic from iHerb which is gonna arrive soon.
I think about it this way - if I was using fluconazole (which is very hard to get to here) according to the instructions I would have to use a very similar dose and it would make quite a bit more damage than a natural element like Iodine. Not to mention I couldn't apply it topically which is as I've noticed essential for my case.
So, so far my 50 cents for anyone with serious problems with Candida - definitely go gradually, but don't be afraid to go to high doses, be careful but at the same time relentless.
Hopefully I can post here one day saying I've beaten the infection completely. Thank you to all for this information!
