Honestly, when trying to quit my trigger time was right after work. So the first few weeks/months of sobriety, I cleared out my wallet of cash, checks, credit cards and made it very difficult on myself to have the means to buy. I also had to take an alternative route home for awhile as my damn car seemed to be on auto-pilot to the closest convienance store. A lot of what was uncomfortable but helped me was changing my routine, like I said uncomfortable, strange but with time it becomes easier. If you have support, and your getting the urge call someone, make another plan, change your thinking to "ah just one" "I'll keep it on the down low" "WTF I'm not that bad of a person" "Afterall it's my only vice" "Damn work/family/kids is stressing me" "Oh it would be nice to unwind" "Oh what the hell I'm a drunk anyway" "One last hurrah", to "Just for today I will not drink, I CAN do this".... be strong.
