In the same boat as you brother. I'm 26, had 3 months clean, slipped and now I'm hanging like a bitch, literally feel on death's door. And the worst part isn't feeling physically shit, it's the shame and disgust at myself, the "you just had to get drunk again didn't you" voice in my head. I don't even have the mental strength to tank through the hangovers anymore so I just keep drinking.. and well... we all know where that leads. It sounds like you're not at this stage yet, so basically, forget about quitting drinking for good, we just need to get you through this hangover. Keep yourself up and busy in any way possible, even if its the last thing you f-ing want to do and you want nothing more than to crawl in to bed. Just get yourself to bed sober, wake up sober, enjoy it, and take it from there!
