Don't think I would stay on Keto, but it might be a good idea to start off with it. Then ease into a Paleo diet, which IMHO is the place you want to be going forward.
Sweetened tea has more sugar than soda. Just drink water and nothing else. Animal fats, fruit oils (avocado, olive oil), protein and vegetables. It will AMAZE you the difference it makes. If you add in exercise it will be even better. Then get off of the meds.
I wish you luck, sugar is a highly addictive POS!
