Sleep Insomnia

I'm battling trying to get a better grip on my ADHD and my biggest problems is Insomnia. I've tried natural herbs, teas even doubled up and taking them two or three hours before bedtime. Nothing much is helping, either I just dont sleep or I wake every 2 or 3 hours and my head goes into action.

What do some of you that also have sleeping problems use or do to overcome this issue. I become such an emotional wreck without sleep, it's embarrassing.
