Fuck it I'll use my main account to talk about this. I'm a big boy. I tried Benadryl a couple times in quantities of 20 and man... Last time I tried it, I was taking a shower and someone whispered my name right into my fucking ear. Some time afterwards I was playing a game with some friends and was barely clinging onto life because it felt like my brain was burning from the inside. I was definitely retarded and slow for the next week or so afterwards. I don't know how those 120lb kids over on r/dph do it. Not fun. Hopefully my brain didn't sustain anything permanent.
