That said, this doesn’t median they can’tmake girlfriend drowsy, and also taking them with various other antihistamines, alcohol, or drugsthat influence the central nervous system (bupropion, benzodiazepines likealprazolam or clonazepam, and others) can produce substantial additive effectsthat might impair your capacity to do decisions or operate a vehicle.
