the drug their always advertising is lunesta or lunestra, something like that. Try to not eat within ~2 hours of going to bed, and do more relaxing activities during those 2 hours. Not necessarily meditating that whole time, just do activities that don't require a lot of physical or mental exertion, you want your body to start slowing down by the time you go to bed. also, like jcb said, don't watch tv in bed, as that will tend to stimulate you (more so with some programs
).
