Haven't been sleeping well of late which is highly unusual for me, but anyway just started taking Restoril last night. 15mgs kept me alseep for 4 hours then awake, though I was able to go back to sleep. I awoke with a headache. Is this a common side effect? Took 30mgs tonight to see if I can sleep through the night. Worried that I won't be able to wake up in time for work. Your experiences: pros and cons, grately appreciated.
