i' m telling a little bit more ... i got this disease 11 years ago ... i tried a lot of different stuff ... beginning with SSRI (Selective Serotonin Reuptake Inhibitor) ... a standard medication from neurologist in germany after i told about hppd ... this is not good and didnt helped ... it becomes even worse ... optical perception problems got stronger and it really really didnt helped ... doctors cant help cuz they dont know anything about it. u even know more about your illness than any kind of doctor ... this f*cked me up really hard ... i tried different substances without success ... i thought there is no help ... i told doctor what hppd is and he could not help me very much ... this desease is not very funny cuz no one knows something about it, i researched web to get more informations about this freakin illness. then i found this forum a few years ago ... people just tryin all kind of stuff ... publishing experiences ... but nothing seemed to help very much ... crazy meds with a lot of bad side effects ...
i got help by myself and meds kind of NMDA receptor antagonists seems like to help ... i just wanted to post that here, maybe someone has same experience ... no response is okay ... but a little bit sad ... no one here want to talk about it or has experience like me ...
