Funny, I was a wino and also immed started juicing once I quit. Great, isn't it? I am amazed how much more energy I have at the gym. I am only 6 days in.
I hear you on the sleep thing. I could not be more awake (midnight where I am) and hope my sleep clock resets soon. I took a leave from work to come off both the wine and valium (i had been warned by my doc that I would likely not function well for the first few weeks) but that won't last forever.
Hang in there and keep logging on. Last year I was going strong and stopped logging. I didn't attend AA either. I promptly returned to drinking wine at my local bar, where I read instead of socialized! Suppose that was my way of "not drinking alone" and not facing the empty bottle in the morning. Oh, as an added bonus to my stupidity, I would then get home, pass out, awake at 3am with a racing heart and start pounding Valium. Denial is amazing!
