You should avoid driving if you're feeling tired.
Although I hate sleeping pills I do have to sometimes take them myself when other things I try don't work.
But here are a few things you can try to get to sleep without sleeping pills.
Avoid Caffeine
You should avoid anything containing Caffeine such as coffee, soda etc about 3 hours before bed.
Caffeine keeps people awake so it should be avoided.
Avoid electronics before bed.
You should try to shut off your electronics an hour before bed and then try reading a book or doing something else.
The light from electronic screens has been known to mess with our sleep cycles.
Try some warm milk.
I'm not sure what it is. But if I drink warm milk before bed it sometimes puts me to sleep.
