i understand what you mean. if i didn't have insulin issues i never would have noticed myself. as it stands now - when i'm eating really "clean", i can easily tell the sugar rush and crash. but i had to take all sugar, incidental as well, out of my diet for a few months before it became readily apparent that i can be a real spaz. what's interesting to me is, i have a friend who is clinically depressed. and he self-medicates with alcohol - so it makes for interesting times. but man the tuesday thru thursday after one of his binge-drinking weekends - he is hell to be aorund. the thing is, he's well aware it's a serotonin crash - doesn't keep him from making everyone around him miserable anyways.
