To paraphase WC Fields: quitting is easy, I've done it lots of times.
I quit and started back up over and over. Quit and start. Each time the withdrawals got worse, each time drinking made me sicker. I finally said "NO MORE" and haven't had a drink in 14 months, 14 wonderful happy months, I might add.
CarolD says: you have to want to be sober more than you want to drink. I found that to be true. My attempts at quitting were really just attempts to 'control' my drinking, not give it up for good. But now that I have, I wish I'd done it sooner.
