Everything you've written about is familiar to me...and I don't have bipolar disorder.
To me it was just the normal cycle of things inside the insanity of chronic alcoholism - the obsessions, the manic highs and lows, the almost endless tug of war between what I should do and what I want...
I stopped drinking and - it took months rather than weeks - but I have returned to a state I remember as being normal for me before I started drinking.
I'm not a dr tho and I wouldn't diagnose here even if I was - I do agree with just about everyone here in suggesting a consultation with a Dr. might help.
