"this has helped me tremendously from day one. i have had trouble sleeping for over 20 years. i was taking the generic for benadryl for the last twenty years. it would work some of the time but i woke up groggy and some nights i still would not sleep. i was reading the link to people that took benadryl or the generic for a long period of time and it increasing your risk of alzheimer&#039;s and i panicked. i&#039;m 46 and did not want to chance taking it so i went to the dr and he prescribed this. what a lifesaver. i sleep every night for at least 7 hours. i wake up refreshed never groggy. i have had no side effects and i have been taking it for 6 months.  i wish i would of known about this years ago."
