You got through it. Think of how good you will feel in the morning when you wake up, KNOWING you had the strength to stay sober another day. The alternative being feeling like utter crud, both physically and mentally, if you had given in to it. I know THAT feeling...and I am glad that you won't be feeling it tomorrow!
I managed not to drink today, too. And now I'm wide awake at 2:00...LOL!
