Whilst detoxing, I slept loads didn't feel like eating much so I drank lots of antioxidant smoothies, took vitamins b12 and Vitamin D. For me its been very much one day at a time, when the cravings came I tried to distract myself by watching a movie, playing a game etc. In my first few months I always had a glass of a soft drink in my hand, constantly! I was initially worried about that, but my therapist told me not to be as it was keeping me sober, eventually I found that "glass holding" diminished completely. Sweets helped loads with the cravings too, Im now looking to combat my sugar cravings lol. But im in a good place to do that now! I went and still go to AA meetings regularly and visited SR at times of difficulties is very important for me.
My advice is do whatever you need to do to stay sober. It doesn't matter what you do so long as you don't pick up a drink! One day at a time.
