I used to get like that - binge for a few days, then i realize I needed to cool it, felt like crap, irritable for a while while not drinking and then started feeling great again, so i decided I wanted to drink again and on and on and on, vicious circle.
finally, i realized I'd had enough, and I currently feel great. My mood has stabilized, I'm more focused on my life and I have a higher self-opinion than I did during those short bursts of cyclic sobriety. I can't guarantee anyone would have the same results - but it's worth a try. For the record, I'm at about 43 days right now. Around 30 is when I really started noticing significant differences.
