I've been trying to quit drinking for a couple years now and have had a lot of 'setbacks' where I jumped off the wagon. But I always got back on and tried again. The people here helped a lot, encouraged me to start over and not beat myself up.
I hope you can get the help you need to stop drinking soon. Your doctor may be able to help you get thru withdrawals safely and more comfortably. And once you get past the w/d, stay sober one day at a time.
We're here to help you any way we can.
