I think my condition is caused by usually mixing differant drugs like 2cb, lsd, shrooms, 25I nbome, noids, mdma, amphetamines, ketamine etc. mostly with weed. I have been more or less ok with my symptomes but since i started using ritalin a bit more than a week ago 10mg twice daily it got worse, should i keep using it or will it keep getting worse. I have also recently tried Sertralin, seroquel, diazepam and mirtazapin. Everything seems to make it worse exept diazepam. Any ideas for treatment other than these drugs? Which drug(s) helped you the most with symptomes of hppd?
