How old are you? Older people very often snooze after a meal (babies too). I doze off a little after a long day after dinner and it's very warm now in Florida, but not to "coma" level. I agree with checking diabetes (is that the same as glucose?).
Some diabetes has nothing to do with being caused by food, it's genetic and is one of the markers that showed up in my 23andme gene test (type 2 I think). When I told this to a friend who has had diabetes for a long time she looks at me and said it's pretty late for me to be getting it, I'm 61.In your case better to be safe and have it checked out.
