Saz, medical science is divided over what is known as postprandial somnolence, or "why I fall asleep in lectures after lunch." Some say that it is the "alkaline tide" from the neutralising of so much stomach acid. Others say that the blood flow of the body is switched to the "Celiac Axis," depriving the brain of blood and making it sluggish with piled up metabolic byproducts. Me, all I know that when they used to show xrays at Parkland Hospital right after lunch, the sound of foreheads hitting desks almost kept me awake.

Hm, I think I'd tend to subscribe to the latter school of thought; the blood flow being redirected to the digestive process and the brain growing sluggish in the meanwhile.
Of course, sheer boredom (like being in a droning lecture or looking at exhilirating X-rays [img]tongue.gif[/img] ) sure doesn't help!
