<<Disclaimer: Verify this information before applying it to your situation.>> Too funny. My Uncle has always been known to drift off. He actually fell off a chair during a Christmas concert. He often had car accidents which he confided to me was because he had fallen asleep. He has been diagnosed and gf for about 2 months. So far no calls from the emerg. department to pick him up. He has also been severely anemic all his life. Hopefully both problems are cured now!!!Probably the 2 are related...anemia and the need to sleep alot and ability to drift off in any situation.
