Positive experiences
“Benadryl works the best when there is nothing else I can do and I take it a lot but probably not the best way to get sleep.”
“I hate to rely on it, but our old friend Benadryl works pretty well.”
“Benadryl helped, but I had to take two to four pills each dose and two to three times a day.”
“I have even tried Benadryl and it did helped, but I don't want to hook up on it.”
“took NAC, Quercetin, Vitamin C, zinc, and Benadryl. NAC and Benadryl per my MD. I was better 48 hours after being diagnosed.”
“I'll also take a Benedryll on occasion as a sleep aid if need be”
Negative and mixed experiences
“i can't sleep at all when i take that stuff. Makes me paranoid.”
“Had insomnia and tested out a Benadryl and trazadone. Felt weird and nervous but it let me sleep at least.”
“Does put me to sleep pretty well, but I wake up the next day feeling drowsy and horrible. Also not a great supplement for an athlete to take due to causing heat intolerance.”
“I have had experience with diphenhydramine but it ended with less than normal sleep.”
“1/2 benadryl actually helped me fall asleep - until it stopped working.”
“I'd also cut Diphenhydramine, I suspect that it cant be good long term...Diphenhydramine is not an ideal sleep aid. May impact your memory into the following day.”
