I took 150mg once because that's all I had so I know I'm not allergic to it or anything. I weigh around 175 pounds so I was wondering how much to take to get ALOT of hallucinations. I will be with my friend who will be high aswelll and 2 other people who will be completely sober. I know that diphenhydramine isn't something that's fun but I want to experience it once and get lots of visual and auditory hallucinations but not overdo it. I want to take atleast 400mg, would 600 be too much?
