Congratulations on 15 days - that's really an accomplishment.
There were days (nights mainly) when I thought about people who could go out and have a drink too. I was pretty envious I guess.
The good part is that those feelings pass (as you've found out). I wanted a drink a couple times during the last two days, but I'm loving sobriety today - it was a really positive day. Kinda like the weather: give it a day or two and things will change!
