Congrats on the weight loss and healthy habits Dave!

Alcohol is indeed very much connected to blood sugar levels. I have done a fair amount of reading on it and in more than one place have read that one of the most common forms/causes of alcoholism is hypoglycemics (i.e. people with low blood sugar) who "self-medicate" with alcohol! These are folks who take in a steady supply of alcohol in the evening, usually don't eat breakfast, etc.

My mom, brother and niece are all Type 1 diabetics--niece diagnosed at 11, Mom and bro at 35! No other Type 1 diabetes in my family though. My dad, I think, has the above-mentioned low blood sugar--alcohol problem. I myself am hypoglycemic and have to watch my alcohol intake, in addition to avoiding too much sugary stuff, and caffeine-containing drinks (which also cause blood sugar crash). I can have a treat or dessert if I have had enough protein beforehand though...

You can probably have a drink now and then but make sure you're eating properly and keeping with your exercise--sounds liek the extreme change in habits caused the slump. One drink a day is meant to be good for you!
