El, in spite of the numbers, congrats. I completely agree about the relative importance of the control in this as opposed to the totals. I sit here tonight writing this after going out with a buddy to my favorite little pub that has about 32 delicious beer dispensers on the wall, had a great time, drank exactly 2 beers (picked for their flavor and not obsessing on which would be the highest alcohol!), and then came home and had one more and I'm good.
Before, as with your pattern I think, this would have been one of those 3-4 nights of serious boozing, and even if it was a hangover day I would have had a few more just to escape that pit and sleep a little harder. I chose to end the drinking early tonight so I can get some stuff done tomorrow to prepare and have even more fun in another day or two on vacation, and it wasn't even an internal battle...absolutely baffling. I certainly may even overdrink next week, but it really feels like I'm finding choice, instead of riding a wave of those boozing/hangover days that always seemed to be running on their own selfish schedule!
Hip, hip, and hooray for control of drinking destiny...even if we can't control our parental expectations!

PS: Hope you can find a magic tea or something to help with the nausea. I haven't noticed that problem, but I'm sort of an iron gut.
