I'm not trying to be rude, but this sounds reckless. You absolutely should not be driving while you have this issue. Also, consider that you may have a sleep disorder.
I appreciate that this sucks if you live in an environment that requires you to drive, but you are way too blasé about something that runs a decent risk of killing someone, and is absolutely not normal.

In England this knowledge potentially tips your actions from accidental death into manslaughter.
You need to fix this.
As other people have said.. yes, you should never drive until you get this issue taken care of.

This sounds pretty dangerous
So, I should never drive? Not OP, but I experience the same thing. Driving just makes me tired. I've tried running A/C at full cold, caffeine, loud music, audiobooks, etc. Nothing helps. The strange thing is, outside of driving I don't get tired or want to fall asleep except at bedtime. I don't drive when I'm drowsy. Driving make me drowsy. The bad thing about it is I usually don't realize that I'm getting sleepy until after I've dozed off once. Then I've got to keep myself awake long enough to get to the next rest stop. 20 minute nap and I'm good to go for another few hours.
