Hey, yeah I carb count and always have done. Beer raises my sugars by maybe a unit or two so is mainly what I stick to. Cider has too much sugar so my levels spike too much and vodka acts much like insulin, lowering my sugars - plus if I have any mixers, very few clubs will do diet mixers which can be complicated.
I don't generally bother counting the carbs in drink, I find alcohol is too unpredictable to rely on the carbs alone so have gotten used to specific drinks and how much insulin I generally need for each (in my case light beer - Coors light etc).
