I use to have this problem, when I was going thru the
"change". Then when I did sleep, I kept waking up. I found
out, I have restless leg syndrome.Now, I take a pill, and
sometimes I spray lavender on myself or my bedding.
You can get the lavender spray at the Bath & Body Shop.
I hope you stay awake while your driving. Sorry, you are
going through this.
Take care.
