In the county jail I was at, nurses came three times a day to give inmates their prescriptions and you could also request Tylenol or a 25mg Benadryl. I got DPH three times a day and stored each pill by hiding it under my tongue after the nurse checked that I had swallowed it. Every two weeks I would have my accumulated gram dose.
The first time I took them at night and basically went insane in my mind. Being confined to a small cell with no way to smoke or decompress while tripping on a deliriant was awful. Officers would come by every hour for checks, loud as anything, and I would just lie there terrified.
The second time was the real nightmare. I took them about an hour before dinner and happened to get called to serve food. I could not figure out how a hairnet works while everyone watched and laughed. Inmates were yelling at me because their food was delayed. Then at my table, one inmate pointed out someone upstairs and the next thing I knew someone was running up and attacking the guy, trying to throw him over the railing. Officers stormed in and forced us all to our cells.
Then my section got called for cleaning duty. I stood around unable to function while others mopped. A guy kept asking me questions and I could barely respond. He eventually said I looked like I was on something and to go lie down. I made it back to my bunk and spent the rest of the night in a haze of shadow people, phantom voices, and absolute confusion about what was real.
The aftermath was two days of severe brain fog, headaches, and a lingering sense that reality was not quite right. Doing DPH in a confined space with no control over your environment and people constantly around is genuinely one of the worst decisions I have ever made.
