I am wondering if I can get some advice from a Doctor about having to take otc Diphenhydramine HCI 50 mg every night. I am currently taking other medications as well, Tegretol 400 mg daily- for mild epilepsy, Aciphex-gastric reflux, Uracit K-for potassium & kydney stones & little pills to make me pee. I have had trouble sleeping for years & did a sleep study about 6 years ago, was told I had sleep disorder. Hmm....well I kinda knew that & wasn't told how to deal with it. I have been taking the sleeping pills & they help but don't seem strong enough so every few nights I take 2 of them. They give me a bit of a hang over next day & takes me a while to wake up next morning, but at least I sleep. Question is, are they harmfull taken long turm? thanks in advance, I really appreciate your help.
