Hi b729
Noone here can tell you if you're an alcoholic or not - but if you're drinking so much on a regular basis you're scared of withdrawal, I'd suggest you're drinking too much - wouldn't you?
If you're concerned, see a Dr to make sure you detox safely - then try not drinking for say 3 months (6 would be better)...
if you don't have a problem you should be able to handle that idea without reservation, you should be able to stick with it with no problem, and you shouldn't obsess about drinking while you're not doing it
