Diphenhydramine hydrochloride, commonly known as Benadryl, is an antihistamine that can cause drowsiness as a side effect. Many people use it as a sleep aid to help them fall asleep. However, it's important to note that while it may help with falling asleep, it can also lead to grogginess and drowsiness the next day. Additionally, long-term use of diphenhydramine for sleep can lead to tolerance and dependence. It's best to consult with a healthcare professional before using diphenhydihamine or any other medication for sleep. **

Diphenhydramine, on the other hand, works by blocking the action of histamine, which can induce drowsiness. Benzodiazepines are generally considered more potent and have a higher potential for dependence and abuse compared to diphenhydramine. **
