This is what the pre-op psy exam is supposed to help flush out. Get to some addiction counseling / AA. Several bottles of wine a day, sadly, makes you an alcoholic. You seem to be accepting the addiction to wine, now you need to step up and get some help. Alcohol is in no way a healthier option than food, I don't see how you can justify wine as being healthier. 2 bottles of wine puts you into the 1300 - 1500 calorie a day mark, and with no protein or other required nutritional value... it's pure empty calories. So it's really no better than soda from a "health" standpoint.
I hope you do get some help... this is bad on a few levels for a non-altered person, worse so for a WLS patient.
