Welcome Crimson
This is my first day also, I was a lot like you living in denial. I drank every night but went to work the next day and did my job so didn't think I had a problem until recently I started breaking my own rules drinking earlier and stronger drinks. My hangovers suddenly changed from hangovers to withdrawal symptoms. Shaking hands, anxiety, sweating and feeling weak.
I hope that in a years time we are both still posting on here about our success in quitting alcohol. Good luck we've both taken the first step by admitting our problem.
