Do you have a routine for going to bed? I found it has helped a little bit with me.
Nothing sugary or caffine after 7pm, no heavy night time snacks or late dinners, I usually keep the lights dim after 9pm and have the tv on low, or just off. Relaxational music can help.
Sometimes I will make a mix of chammomile and chrysanthemum tea, but i dont like to fill my bladder before bed.
A med that helped me was inderol, a blood pressure med, very inexpensive, its been around for a while and not addictive like sleeping meds or benzos. I found buspar helpful at night too. both of these helped me get asleep but not stay asleep.
