Any time I have tested after beer, it hasn't raised me much, or at all. That doesn't mean it isn't carby and somewhat inadvisable, but I think the alcohol may offset the carb content to some degree. Try a little, then test- maybe after 1 hr then again after 2 hrs to see what it does to your levels. If it raises you too much, maybe switch to spirits. Spirits drop my BG levels like a stone, so I would probably have a couple of whiskys first then drink my beer. Your mileage may vary, but if you test cautiously and act accordingly, there should be a way for you to enjoy some of your beer. Good luck with it!
