As I posted earlier in the thread, I have not drank in over a year now. I will summarize some of the highlights of my situation and maybe you or someone else can take something from it.
I loved beer. Good craft beers. I long knew I had a bit of a problem. I would take beer to bed with me and drink before bed to help me fall asleep; as you described, I would be anxious to get from non-drinking situations to drinking ones, etc. I am an anxious person, and drinking and anxiety were a vicious cycle. I would be anxious, so much so that I could feel it in my chest, so drinking would be a short term solution. Then when I would wake up the next day, the anxiety would be back and be worse - hence the cycle.
A book called "How to Stop Worrying and Start Living" was a book I read a month before quitting that changed my life. I read it front to back a couple times within a few weeks and really absorbed it. It helped tremendously on my outlook on life and my anxiousness. I think I drank to cover up other pain in life as well (death of my mother, ####ty day at work, etc), instead of dealing with my problems head on. Drinking was a way to put off problems. Additionally, I also really didn't like myself. So I read a different book simply called "Self Esteem" that really helped me to like myself a bit better. I think those were the foundation to help get me through the quitting and life style change.
The hardest part for me was the first few weekends of not drinking. I was like WTF, I've come home and had a beer on a Friday every week for 10 years since college. I don't have great advice on getting through that. It's ####### hard. I drank n/a beer and still do and that helped a bit. I still enjoy the taste of beer and love the fact that it doesn't have an effect on me. After a few weeks of coming home and not drinking, either during the week or on the weekend, it starts to become routine. Social situations (work functions, sporting events with buddies) really had me worried. Just ordering a diet coke or tonic water with a lime made it looking like I was drinking and it was no big deal.
Those are some of the highlights for me, hopefully I didn't ramble too much.
