Kimbo,
I have done that before. Gone out for a meal had quite a bit of wine and because I know by bg will drop slightly from the wine i've gone ahead and had a desert but not taken any extra insulin... just relied on the wine reducing my levels a bit. (still taken my normal shot though... just none extra)
For me, the way I see one large glass of wine is like one or two units of my novorapid (fast acting insulin)... both do the same thing in terms of lowering bg. Obviously I'm not recomending drinking instead on taking insulin... but now and again what you're asking is ok.
I dont really drink anything other than red wine, so I'm only aware of the effects wine has on me. Also larger but that doesnt seem to make my bg go either up or down at all.
It may be a little different if you are type 2 I supose, but i'd imagine the alcohol would still have the same effect... but obviously if you went high you probably couldn't control it as much a s a type 1. I don't know enough about type 2 though... think i might try and learn a bit more
