It doesn't happen that often, but does happen to me. I think it happen more when I have carbs (specifically potatoes, which I do not have very often).

I mentioned to my Dr. at my 7 wk visit last week. He said it might be dumping syndrome and didn't seem too concerned. I don't have sweats or diahrea (which I read as being dumping symptoms), I just get tired and it subsides after a half hour or so.

When I eat sugar or some other carbs (mostly sugar though) I get super tired for about 20 minutes.

I dont even take a bite of dessert anymore in restaurants cause I want to put my head down and rest and my family thinks its rude...lol

When I eat too much, this happens to me. I just have to lie down and, like you, half an hour later I am fine.

I told my wife this is probably what the whole tiredness after Thanksgiving meals really is about, not the triptophan (sp?) link. I'm guessing that eating too much triggers the body to go down for a bit until it can process the load a bit.

Me too! Even today I had veg soup (without potatoes) and I needed a nap. Lol. I think it's from being full also.

Sounds like a sugar issue. Have you ever tested your blood sugar? If you have assess to a meter, I would take your blood sugar throughout the day and see what it is before and after eating and again an hour after eating. Some people who are insulin resistant will over produce insulin after a meal which causes blood sugar to drop.
