"i took this as a sleeping aid due to a very hectic schedule that was stressing me out. it did help me go to sleep and stay asleep but i noticed that i was somewhat dizzy at times during the day. over a six week period the dizziness became worse. i went to an ent thinking perhaps i had an ear infection that was messing up my balance. he told me to discontinue the diphenhydramine and try valerian root (i didn&#039;t want to use any more drugs) and it would take time for the drug to get out of my system. i&#039;ve been off the med for a week and still have some dizziness going on. this drug is definitely not for continuous use!"
