insomnia
"I have read so many things and do not know what to believe. I have post traumatic stress disorder and have taken sleep aides from the health food store which left me with Vertigo and not feeling well. I have not had any of the usual  side effects with Ambien and it leaves me refreshed however I do have one weird side effect and I was not sure at first if it was the Ambien. But it is. I am usually a person who is cold and likes the heat. But I have gotten heat sick several times and living in NYC where there is no air and we are constantly having heat waves it has made me sensitive to heat. I am super sensitive and usually if there is a side effect to be had I get it but really I have not had anything except the heat exhaustion. I mean  sweating, etc."
