At first (and especially now) I did notice a decrease in anxiety.
Looking back, I guess on day five or so I was feeling a sort of "coming out of the fog" feeling. I was expecting that to happen on day 1 or 2 of no drinking... That's another thing, I feel as if around day five or so, I would get discouraged (I tried to quit drinking a few times but failed.)
I have just a tidbit of advice... Just don't get discouraged! If you feel all those things that you mentioned today, and then don't feel them tomorrow, please don't feel as if "nothing" changes when you become sober. Or that they change, but then just go back to being the same old, same old. Things really do become very different, or at least much, much better.
Let's see, some other things I was feeling around day five:
thirsty, like you!
vivd dreams
a sense of accomplishment
frustrated
irritable
tired!
Good work on your sobriety. You're taking an incredible step!
