Maybe make a list of all the benefits of being sober. That might help you in your resolve not to drink. If you have problems going thru any withdrawal symptoms please talk to your doctor. Be safe while detoxing.
As far as support, we're a very supportive group here at SR. THere is also 'real life' support, like AA, LifeRing, SMART recovery, and other groups. In the Alcoholism forum there are 'stickies' at the top of the page about the sobriety resources available.
Welcome to SR! Glad you joined the family!
