You sound like I did when I first tested the water of sobriety. Finally went to a Doctor, convinced myself I was done, and quit for like 5 days too. Then back to the races. This is a cycle that can last a lifetime. I would challenge you to find some AA in your area. There are meetings worldwide and I am sure you can find some if you look around. Without knowing where you are from, here are some resources that can help your search:
International A.A. Meetings,Find information on A.A. meetings worldwide - :: Alcoholics Anonymous :: -
No luck there, scroll down below the US here and you can find more country specific listings with phone #' s you can call:
AA Intergroup and Central Office Phone Numbers
It's hard to do it alone.
