  1. I got hppd a few yers ago. I'm totally fine now. But I thought about it for a while and came to a conclusion that hppd might be the disease of neurotics , ipohondriacs , depressives. Not to be condenscesing or anything , I myself was prone to anxiety and depression. And its ofc not what u are but what u do with it , in this case. But just how many of us would describe ourselves of a neurotic predicament? Not to say that hppd is fake. But I strongly suspect that there is a huge link to having a certain type of a personality. That I conclude from what I myself was prior to working on myself , on the info on the net , and also on the posts on this website. Many are ofc totally rational and sober minded, but cmon , just how many reek of neuroticism and ipohondria? Once again, I totally was in that boat myself, and who would blame a person for neurotisism who just got his world turned upside down. But I still think there is a very definite neurotic/ipohondraic 'flavour' that imbues much of the hppd-sufferers communities. So it would be interesting to know how many of you would consider themselves of a neurotic/ depressive/ ipohondriac predicament prior to getting hppd.
  2. So, awhile ago I began investigating the role acetylcholine might play in HPPD. This was mainly driven by the fact that my case of HPPD was likely caused by diphenhydramine, an antihistamine with potent anticholinergic properties (i.e. it "blocks" the action of acetylcholine). Other driving factors were the fact that many people seem to at least have a temporary worsening of HPPD symptoms when using anticholinergic/antihistamine/antimuscarinic medicines and also to the eerie similarities between central anticholinergic syndrome/anticholinergic toxicity symptoms and HPPD symptoms. I decided to run a little experiment. I went back to my roots of taking diphenhydramine in a somewhat recreational manner. I was having issues with some nausea of unknown origin (though I likely suspect it has to do with caffeine because at the time I was pounding 2-3 energy drinks back-to-back in the morning, diphenhydramine has antiemetic effects) and insomnia (also probably due to caffeine and also potentially due to my tapering off of clonazepam). I decided to keep the doses relatively small, no more than 50mg at a time and no more than 100mg per day. My condition at the time and also as of present left me quite sensitive to the "recreational" effects of diphenhydramine so a 50mg dose was pretty much enough for me to feel the full effects I used to crave. I kept my dosing to only when I more or less needed it, when I felt nauseous and at night approximately 1 hour before bedtime. I did not notice an immediate worsening. However, as the "experiment" progressed over these past few weeks, I noticed my symptoms started to get worse. In particular my double-vision/ghosting and trailing, my two major symptoms. These symptoms have remained at this worsened level since the end of the experiment (last week). Of course, some might attribute this to the caffeine since so many people have trouble with it. Caffeine for me is not an issue except for mild, temporary worsening of symptoms at high doses and the worsening fades when the caffeine more or less leaves my system. Getting back to acetylcholine. Acetylcholine acts as a neuromodulator and messing with its function is known to cause neurological/psychological problems. It would make sense that HPPD could be caused by messing with acetylcholine. I mean we think HPPD is a sort of sensory disinhibition and acetycholine is a neuromodulator thus if acetycholine levels are decreased significantly it would make sense for sensory disinhibition to occur.
