A couple thoughts to March. First off detoxing is a very difficult process to go through especially at home. Don't be afraid to go for medical help if you start to get severe DT's. It's nothing to **** around with.
Second, AA isn't one sip you're done. I had alot of misconceptions about recovery, AA and treatment (therapy) before I went to detox. I just wanted them to detox me and pow everything will be fine, I'd do it on my own. Well I was wrong and wouldn't be able to do this on my own. I've smelt alcohol on members breath at meetings and although it's not encouraged AA only requires the desire to stop drinking.
One thing with all your problems, yes drinking leads to unhealthy and lazy behavior but just because you stop drinking, all these don't automatically change. I'm learning that every day which is why the 12 steps are so important. Some of these things might change like the smoking and work but it still takes alot of effort and desire.
Good luck to you bro.
