I have sleep issues, but they're due to menopause. Since I started working full-time, I have NO problem getting to sleep. But there were times when no matter how long I laid in bed, I couldn't get to sleep.

I've found that drinking pop (especially one with caffeine in it) or eating spicy foods before bed has something to do with insomnia.

I'd talk to your doctor. Maybe he has some relaxation techniques you can use.
