A lot of problems come from alcohol. In the first place, as Miyr said, it contains a large quantity of carbohydrates. Sugar is a very simple carbohydrate, and ultimately doesn't matter much; it's carbs in any shape or form that will raise your blood sugar.  MY insulin regimen actually is set up so  I take insulin based on how many carbohydrates are in my meal.<br/><br/>Secondly, because I am a diabetic, I am much more prone to liver and kidney problems., which alcohol can cause.<br/><br/>And thirdly, alcohol itself is an insulin antagonist; it makes your insulin have to work harder to accomplish less. This isn't a big deal for most people, because your body  can handle it by just making more insulin. Not a great idea, but manageable. Ina  type 1 diabetic like myself (their is no insulin production whatsoever) that can quickly cause a problem.<br/><br/>It is, in fact, quite possible for a few beers to kill me. Or put me into a diabetic coma which I may not come out of. And even if I do come out of it, it is likely to be with<strong>severe</strong>brain damage.<br/><br/>In closing, I would like to say that being a diabetic sucks. You have to tip toe on egg shells with everything.
