Insomnia
"Diphenhydramine is an extremely effective sleep aid. It takes half an hour or less for 25 mg to knock me out. 



The biggest problem I have with diphenhydramine is that it makes me feel kinda&#039; groggy and nauseous the next day. I feel like I&#039;m walking around in some weird twilight and food just doesn&#039;t taste good to me.



Still, out of the three sleeping pills I&#039;ve tried, diphenhydramine is by far the most effective. Ambien made me feel like I was on a roller coaster and melatonin mainly makes me fall asleep a little faster."
