Ashley had some good pointers in the thread Jim bumped up for you. I myself love a hot bubble bath to relax in before bedtime.
- Wake up at the same time every day, even on weekends
- Don’t go to bed unless you feel tired and sleepy
- If you don’t fall asleep within 20 minutes, get up and do a relaxing activity in another room
- Listen to soft music, flip through a magazine, or read a book to induce sleepiness
- Take a warm bath
- Avoid naps, especially after 3:00 p.m.
- Exercise regularly, but early in the day and not six or fewer hours before bedtime
- Keep your bedroom cool, dark, and quiet
- Avoid watching TV, eating, writing, talking on the phone, or reading in bed (keep TVs and all electronics out of bedrooms)
- Don’t go to bed hungry but avoid large meals (and drinking lots of water) before bedtime
- Establish a bedtime routine
- Drink a warm glass of milk or herbal tea, like chamomile
- Avoid caffeine after 3:00 p.m.
- Avoid alcohol within six hours of bedtime
- Have a massage
- Practice deep-breathing exercises or meditation
- Try this exercise: Imagine there are faucets at each finger and toe’s end. Imagine them all running and envision all stress and tension rushing out through them.
When I quit I tossed and turned for just the first few days. I think it was more from worrying about whether or not I could do this quit rather than from the lack of nicotine. Hope something works for you.

I hope one of my suggestions help. Maybe someone else will chime in or try doing a search. I'll see if I can find a thread or two and bump them forward for you.
