Chubz,
I'm 25 days into the choice you are contemplating. 25 days, not a drop. The first week was interesting. I had a little trouble sleeping, 'cause I was trying to really sleep instead of passing out. And, I got my appetite back. No more calories from booze and my body wanted food. Amazing! Sounds like your friends are supportive. That's become a little bit of an issue recently. One guy is actually thinking about hopping on the wagon with me, but a couple others are asking me when I'm gonna start drinking again. If they don't wanna hang out, 'cause I'm not drinking, then f*** 'em. I don't need friends like that. Nobody does.
I feel great, I'm saving money, I've started to exercise a little, the house is clean, and I'm drinking hot tea. You'll need to find things to do instead of drinking. Don't let a stressful day or boredom talk you into, "just one won't hurt".
I've chosen to live again. I don't know where you are with alcohol, but I understand the need to figure it out. I'm 36, and these 25 days are the first 25 consecutive days of sobriety that I've had in years.
Good luck with it. Email me if you'd like. What you want to do is a great thing. Give it a shot.
