Hi, I'm on Day 1 today also! I've forgotten how hard the first couple days are. This is my third cleanse, but my first in a year. I'm going for ten days, my usual.
As for the booze, here's what I can say. The last time I did this I was doing a play with a very sociable group that loved to have a party after every show. I found that just being on the cleanse and telling everyone about it helped me to stick to it. I decided it would be harder on me to miss out on the socializing, so I still hung out with everyone, with my lemonade right in front of me where everyone could see it. After the inital questions and teasing, things went back to normal. It felt good just knowing that I did not "have" to have a drink or food to hang out with my friends.
