Ok let's look at it a different way. If you were newly diagnosed diabetic - that would really stink wouldn't it. You'd probably get angry, depressed, have mood swings for a while over the 'injustice' of it all, but you'd get through it - you would have to.
Alcohol, is no less serious - we just 'fool' ourselves into thinking we can 'get away with it;, but in reality it's killing us, just as much as a sugary cake could be the final 'chance' for a diabetic.
