Don't Use Your Computer/Cell Phone Before Bed (No Texting!!). It's always been hard for me to sleep, and I mean always. But recently I read that a computer's bright lights suppress sleep hormones. I'm not sure if that's true, but not using it before bed sure helps. But then I got unlimited texting and my insomnia was back again. So here's the deal, don't use your computer or cell phone 2 hours before sleeping. It will help you sleep better and better each night.
