My experience is to carb count and dose for the first 2 pints but, if I drink any more (which is rare because I am small and it makes me drunk), I need no more.
I also have a policy to avoid carbs of any kind if my levels are above 10 as I become insulin resistant.
Recently, I have started drinking non alcoholic beer. This has improved greatly in recently years and actually tastes of something other than water. At first I dosed assuming a similar carb content to alcoholic beer. Turns out low/no alcohol beer is also low carb and pretty tasty.
