Do you feel you need to change many things in your life to stay sober?
only ONE thing:
me and my attitudes.
which diet, exercise and all that werent gonna do that.
on this:
One of the most difficult parts of quitting for me at the moment is that I'm able to drink 3-6 light beers a day everyday without hangovers..."
imo thats a lie and just rationalizinf drinking. the most difficult part is making the decision you want to be sober more than ya want to drink.
and dont forget, alcoholism IS progressive. you WILL sink deeper and experience gloom,dispair, and agony like you could not imagine IF you dont stop drinking.
