You can drink alcohol even with type 2 but it is vital that you do so with a snack and in moderation and keep checking your blood sugar levels. Perversely alcohol can lower the blood sugars (though to taste it, you would think that it would be packed with sugar.) with some of the medications that a type 2 might take - namely gliclazide, metformin or whatever.
The danger with drinking and diabetes is that you might be having a low and act and smell drunk, and because you smell of it observers often put two and two togethe and make five!
Whoever told you that you can never drink again has issues with their drinking or others drinking and that is just their opinion. Better to experiment at home - with a friend present - and see how you react.
I had a drink problem - and I was wrongly diagnosed with Type 2 and found that I reacted to it, so made the conscious decision to stop. That was my decision and nobody else could make that decision for me. 7 years dry! Whoopee! My mother on the other hand is in denial and drinking for the two of us!
