I take Lunesta. For 1 year, 10 months. doesn't work as well as it used to but better than nothing. I also take terazosin to keep me from urinating too frequently. One reason I was waking up at nite. My problem is staying asleep. I wake up after 3 hours and then It takes me several hours to fall back asleep. My brain doesn't stop. Doctors have no explanation. I need help.
