Tired!

Has anyone else noticed that for some unknown reason they become super tired all of a sudden? For example, yesterday afternoon I suddenly felt so tired I could not stay awake or for that matter keep my eyes open.  This happened two hours after a normal lunch (turkey hotdog on whole wheat bread and a little mac and cheese)  My guess is that it was too many carbs from the mac and cheese.  (darn kids just love that crap) I could eat the same thing today and nothing would happen. Just wondering if others have this same thing happen to them? Thanks Jim D

I've had this before.  Could be B-12 (check your levels), though I'm guessing it's carb related.  As for why sometimes and not others, could be you didn't eat protein up front, or maybe you are drinking and forcing the carbs further down the intestine, or maybe it's just random sometimes (our bodies act different depending on our immediate calorie needs and pre-meal blood sugar). I'd venture a guess that if you substituted an ounce or two of hard cheese for the mac-n-cheese, it wouldn't happen.

Amazing, I feel the same thing.  Moving around, doing stuff like everything is OK, then WHAM....super tired.  Don't have a clue as to the triggers, cause.  Weird.
