Narcolepsy

[Guest]

My symptons are sudden, drosey sleepiness about twice a day; after lunch usually, and around 7pm. I find that eating activates it quite a bit. If I don't eat, my energy level tends to stay up. The feeling I get is almost like a wave of droseyness, not like the slow, irratable feeling I get when I haven't slept for a long time late at night. Its almost like a chemical feeling. A quick 10 minute nap does the trick. Could this possible be a blood-sugar, or chemical thing instead?

Cheers,
David
