Good for you, TG and congrats on day 3! So glad you didn't give in!
It takes time to get used to being sober - I felt like a fish out of water for a while. The good news is that it gets better - a little bit each day - so hang in there!
(For the first two weeks, I got carryout from a good restaurant each evening - it was something different to look forward to, and eating helped take the cravings away).
