Too many simple carbs. Go with more protein & more complex carbs, while avoiding simple carbs.

That is an urban myth and not true. If anything overeating causes the body to pull from other resources in the body to handle the overload so that may be why one feels tired after eating a huge amount.\n\nThere is not enough tryptophan to trigger the amount of serotonin needed for that effect.

This might be because, you are eating until you are to full. Try not eating so much. You might need to see a dr. My daughter has to take medicine because, sometimes she feels sick after eating. I'm sorry but, I forgot the name of the medicine but, it is a prescription.

Yes, I'm sleepy. I don't know why I stay up so late. Lack of self control, I guess. It's ten after 2 in the afternoon here. I start getting sleepy after lunch and way sleepy around 4.

I had that problem once and it was my caffine intake. I was drinking so much soda that it made me tired in that way. Not sure what your habits are but try drinking water. Its incredible how great it makes you feel if you drink enough. Try water for a week or so.

Try not to have too late a meal. Your body needs time to digest, and being asleep sure doesnt allow that to happen in the best way.\n     Take a walk after your meal, should help with the digestion, and as a bonus it's a little exercise.

It is because after eating the concentration of sugar in the blood increases which leads to ex-osmosis ie movement of water from the body cells to the blood where there is high concentration of solute. The movement of water from the cell results in the reduced metabolism which courses one to feel sleepy.

When I had mine out, hot liquids felt better than cold. But popsicles were a welcome treat, too.\n\nDrink a lot. Take your meds on time (even if that means waking up in the middle of the night). Don't be hungry because it hurts to swallow. Ask for help. Don't lift heavy things.

You might be tired due to a drop in blood sugar. Therefore your body craves something sweet to raise the blood sugar. Other people might crave carbohydrates of some kind such as bread, pasta, or potatoes ie French Fries. Carbohydrates turn in to sugar once they are ingested. If you seem to get tired fequently you should probably talk to your doctor.

Two popular theories atm...\n\nFirstly, Researchers have discovered that high blood glucose levels, similar to those after eating a big meal, can switch off the brain cells that normally keep us awake and alert. \n\nAlso, when you eat, lots of blood travels to the intestinal area to carry nutrients around the body. This is known as shunting. When this occurs, your brain is getting less oxygen. \n\nThe first theory is the more credible, with the second theory being the best applied to why you feel cold after eating (less blood to extremities).

You shouldnt but you might because your body is busy digesting and sorting out good and bad, etc.  You may feel sleepy but check out how heavy the food is or how much your eating.  Food is supposed to give you energy not a need for nap (unless it is turkey and that is b/c of a chemical in it).

Could be your blood sugar putting you through that "haze". Try eating lots of small meals throughout the day rather than the typical Breakfast/Lunch/Dinner. That will keep you more energetic. Also, (this will sound kinda crazy) - but try reducing the amount of hours you're sleeping at night. You suggested you sleep "normal" hours, but I've read that getting TOO MUCH sleep can keep you groggy throughout the day. Try cutting back 1 to 1-1/2 hours and see if makes you more alert during the day.

Don't know where you are, but I certainly hope you are not trying to do your home work in my time zone right now (I'm in Texas).  Because if you are, I can tell you why you are feeling tired.  IT'S 5:00 AM!!!\n\nSeriously, try not snacking before or during studying. Or if you do, eat healthy snacks such as raw vegetables, nothing sugary or starchy.  Go to bed every night at the same time and get up every morning at the same time.  This will train your body and your mind when you should be awake and functioning and when you should be asleep and resting.\n\nThere is so much more.  I don't think I could list them all here.  Besides I'm at work and I have a job to do.

This happens to me sometimes too. I think that mine is from eating too early or too late. I can't eat anything before 10-11am and nothing after 6pm. Sometimes I even feel sick though when I just eat a regular meal.  I don't know the cause of it,but have no other symptoms to indicate a problem,so I just live with it.\n\nIf you are experiencing other symptoms,I would recommend that you speak with your physician. If it concerns you greatly,see your doctor too.

If you eat and then go to bed very shortly afterward, your brain's oxygen is being used by your stomach for digestion.  Change eating or bed time.  \n  Get a dream dictionary.  Some "bad" or "odd" dreams may actually portend good things.\n  I sleep restlessly if I eat either lots of bread or have red sauce (spaghetti, lasagna, etc.)  Pizza, both bread and red sauce, is the worst especially if eaten late.

Try to fit some exercise in your day.  That way you'll feel tired when you actually need to fall asleep, which you probably don't feel tired at, since it seems you're drinking a lot of sugary and caffinated drinks.  Those make you feel the sugar high and then crash after a while, making you more tired than before.  You'll get a better night's sleep, and if you need to have coffee, have one not many.  Eat healthy foods too.  Carbs with sugar make you even more tired.
