An update: I've been on a predominantly carnivore (or keto-carnivore; more fat than protein), animal-based diet for 4 months, since mid-March. Between November and now, it took me three tries at it of not making past 11 days to realise that even making skin contact with non-animal based foods, affected me enough to not be able to sustain the diet and beat cravings. As I handle and prepare food for other people who do eat non-animal based foods, I realised wearing gloves to avoid skin-to-skin contact was a possible solution. And it worked really well!
Mood, physical pain and a sense of internal balance have all improved significantly, worlds apart from pre-carnivore. As for fluids, I kept herbal teas (liquore and pepperment; I love liquore so much, it was difficult to say goodbye) and coffee until about a month ago, when I became ill and tapered off those. Coffee affected sleep significantly. There were many other factors that crossed my mind also, such as coffee not growing locally and its effects on the body particulary in excess.
I don't miss coffee, or herbal teas. It's crossed my mind to switch to something like fennel leaves tea, or teas and drinks of herbs that I can grow in our garden, or essential oils teas and drinks. It's not a high priority because I don't miss those things. I have to say, what really helped me quit coffee is
cold adaptation, or cryotherapy. Cold baths have been extremely helpful!
I took cold baths back in 2013 while first trying out and experimenting with ketoadaptation and the
ketogenic diet, and throughly missed them when I moved to other places without a bathtub. It's great to have a tub again!
