I didn't drink everyday either but when I drank, I drank to get drunk, I stopped being able to tell when enough was enough! Eventually, the once in awhile drinking progressed to 4 out of 7 days a week to eventually everyday! Didn't mean for it to happen, it just did! Then it got to the point I didn't know what to do with myself if I didn't drink, very sad!
I consider myself to be an alcoholic, I tried so many times to control the number of drinks I had to convice myself I didn't have a drinking problem! As hard as I tried I just couldn't do it! After about 100 times of trying to drink just a few, I finally figured out I can't have even one. The craving for the buzz starts after the first drink, not before, once I got that first drink in me I didn't stop until I passed out or was very close to it!
