re: What are your worst sleepy driving experiences

I used to drive an hour to work every morning and had problems with getting sleepy.

Once I fell a sleep just before a red light and swayed over and knocked mirrors with a truck in the lane next to me, that woke me up in time to stop at the light. If I didn't knock mirrors with him I might be dead right now.

But as far as staying awake techniques. The by far best I've come across is to eat/chew/suck on ice. I don't know if it's the sound or the coldness but ever since I found that out I haven't had anymore problems.
