    • Do you think we will or maybe some of us will get answers to this one day? I feel like not enough people know of it to consider trying to help us, especially now that Dr. Abraham is retired. I just want answers. I know the terminology drug induced psychosis is something that gets tossed around a lot which, maybe we have it all mixed up. Some claim damage to gaba receptors, which also doesn't make much sense to me considering there have been the odd case where people have cured their hppd with psychedelics. Why do some get rid of theirs using meds like lamotrigine and keppra, and others dont find success in meds at all. Im sure when RC's become more common, thats when more people will end up with it. Anyways, 11 months tomorrow with no end in sight, good times ahead. 
    • Hi. I have no idea if I have HPPD or I have HPPD through Lyme disease. It started in 2015 in June. Earlier, I was under severe stress by a psychiatrist and drugs that destroyed me. At the end of June 2015, I discontinued Truxal (chlorprotrixen). And I started taking herbal medicines, 5 HTP and melatonin for sleeping because I could not poison this medicine anymore. After a few days when I went to sleep, I got a wavy line and my head was arbitrarily thrown back. I felt strangely at night. When I woke up I saw a lot of floaters. Hell has begun. I got a lot of stress. I do not remember if I smoked marijuana before. But after that I smoked marijuana but I was always unable to enlist. When the floaters were formed, I got conjunctivitis in a few days. I got drops and you're allergic. The inflammation went a bit, but it's not over. Later it was only worse. In August I fell ill with pneumonia. I had a terrible strong cough ... at night I suffocated ... antibiotics did not help much ... I did not have a cold. Then the hell started ... my stomach ached and I had cold sweats. I was lying half-conscious ... as under anesthesia. My head was so heavy that I could not keep my head upright. There was a brain fog, derealization, de personalization, problems with concentration and memory, stiff and strained muscles, visual snow. My eyes started to fester very much, they were burning and scratching. My eyes have been festering for two years. Lists from the eye were made. Nothing came out of the study. I was taking a lot of anti-allergy drops, antibiotics, steroids that did not help either.       What are my symptoms now: visual snow, bfep, eyes are dry and very painful are like tense, floaters, bfep, tense abdominal muscles which hurt a lot, temple pain, I do not feel like eating, lack of libid, diarrhea, undigested food, stiffness chic and back, tight muscles of the whole body, high pressure, sweat, hair loss, terrible seborrhoea, numbness of legs and hands, derealization, de personalization, brain fog, psychomotor anxiety, anxiety, strong depression, insomnia, agitation and fatigue, aggression attacks, my head was supposed to explode, strong eyes ache, views, taste and smell disorders, dementia, photophobia, bfep, CEV, floaters, photopsy, nyctalopia, halos, glare, ghosting, pulsating vision, flicker of vision, loss of sensitivity to contrast, visual glow / visual stress, body shaking,very dry eyes  
    • Hi. I suffer from terrible insomnia since it started. I have to take something to sleep. Has Remeron worsened your symptoms eg visual snow or other?
