Some nights I fall asleep about two hours after taking my meds, but lately I have nights where I just cannot sleep. My pdoc prescribed Lunesta (in addition to my arsenal of meds) and it does nothing. It doesn't make sense to me that some nights my meds make me pass out and other nights I'm just wired. Do you think it has to do with mania? My husband says I have been on the manic side, but I don't think so. Thanks for any suggestions, etc.
