I also take over the counter meds to help me sleep. It's just once in awhile, not every day. Zzzquil contains the same active ingredient as Benadryl. Sometimes I take Benadryl or a low dose of Gravol. Perhaps they interact with my psych meds but I've been taking benadryl to sleep for several years and I'm still here. I haven't told my Pdoc and don't intend to. He'd have a fit and I'd get a big lecture, which always makes me cry.
