You were kinda vaugue on what exactly you took, but I think you meant diphenhydramine. DPH is one of the craziest drugs out there. I've used it 5 times, but stopped after I ODed on it and went to the hospital, then to 3 months of impatient facilities. Those 5 trips were the craziest moments of my life though. I had good trips every time I used it (except maybe the 5th, I remember absolutely nothing and nobody could tell if I was having a good or bad trip). Its probably because I always used lorazepam and weed with it, was prescribed some antipsychotics and mood stabolizors, and also can naturally handle hallucinogens well (experience with psychedelics and disassociatives doesn't prepare you for delierients, but your natural reaction to them does). The mix of drugs I took with it made it difficult to remember a lot of the trip, but the stuff I did remember was crazy. I was once on DPH with two other friends who were just stoned. I don't remember what we were talking about, but we were all just having a chill conversation. One of my friends kept saying "what?" to half the stuff I said, but I was speaking understandably. After maybe 10 minutes or so, he asked if i was talking to another person too. I clearly saw two people there, so I was confused on why he asked that, but I said yea, he's right there. He told me there was no one else there except me and him, and I realized the third person was just a hallucination. Holy shit. Another time, I went out at night to trip with a friend. When I got home I had to sneak back in so my parents wouldn't know I went out at night. I quietly opened the door, closed it, locked it, walked over to then up the stairs, went to my room, lied down in bed, and shut my eyes. Then I was standing back outside in front of the door. It was all a huge false memory. I snuck in, kinda for the second time, but was too loud walking up the stairs and heard my dad call me. I went into his room and told him I was just smoking weed in the backyard (i was allowed to smoke at the time, but he always talked to me if I came back in at night to make sure it was just me). He could clearly tell I was on something else, my eyes were wide open like I was tweaking, I was shaking, I couldn't stand straight, and I was slurry my words and only saying like one a second. He asked if I did anything else, and I said "no, just smoked", then started talking about how I made up with the friend I was just with (we were mad at each other), for no reason. He was really confused on why I was saying it, but don't remember any more than that for that minute of the conversation. Then he noticed me staring, eyes wide, jaw dropped open, at his bedstand. He asked what I was looking at, and I said "synda". I was seeing a 6 foot tall video game character floating next to my dad's bed, and thought it was real. He said "what" and sounded really confused, and I just said "syndra the champion!" thinking he could see it too. He seemed mad, and said in a loud voice "What are you on?". I said "weed, I'll talk to you later" then sprinted into my room. I was gonna write more, but just realized how long this was, so I'm gonna stop here. Adderall lol.
