What can you drink...? Tea (black, white, green, chai, rooibos, tisane), coffee/espresso, water (with or without a lemon or some other fruit for infusion's sake). Prefer a bit of cream in tea of coffee over milk, the fatter the better, if you like your tea or coffee other than black. Those are basically the lowest carb things there are, aside from diet drinks. There's a lot of debate about artificial sweeteners in those though, some tolerate them just fine, others don't... For some they spike blood sugars, others get gastro-intestinal issues because sweeteners are toxic to gut bacteria. But if you test and find them okay, and just drink them in moderation, I don't see a problem. Just figure out what fits you. https://www.dietdoctor.com/low-carb/drinks is a guide for non-alcoholic drinks, https://www.dietdoctor.com/low-carb/alcohol covers the ones with alcohol. But with liver issues one might want to avoid alcohol entirely. I know my liver wasn't amused when I tried a little sip of something 5 years ago. (And that really was all it was. One. Sip. OUCH!). Since I don't tolerate cow dairy well and there's a lot of carbs in a cappuccino I'll only treat myself to one of those at a maximum of one a week, for which I'll pay in a few hours of rheumatic joint pain, and I only allow myself one if it's a day where I walk a lot, so I can mitigate the spike it'll give me afterwards. You decide what you can tolerate, how much something is worth it to you and what you're comfortable with. I know I shouldn't touch cappuccino's, ever. But since my beloved teas have been giving me migraines and kidney stones, it's one of the few things I will allow myself. Because I enjoy it so much it makes my toes curl in joy, and the sore joints are worth it to me. You make up the rules as they suit you, and your meter.
