For the past 6 months I've been suffering from severe HPPD and constant head pressure. I see after-images from everything I look at, can't see straight lines because the lines are keep waving, thick visual snow, slightly moving and breathing walls, floor, ghosting vision, and all other HPPD symptoms. I've quit all drugs including alcohol since then, although I used cannabis a few times I've quit that as well. However after 6 months since I got HPPD the symptoms are just as severe and there is absolutely no relief.In fact the visual snow and afterimages got a little worse than when it started. When do these symptoms start to reduce in intensity? Anyone recovered from it or feel much better?It is causing me an extreme stress and I really need some assurance from people who know about this to get through this. Doctors can't help with HPPD, I've already been to several doctors and went through many tests as well. Please I need your help.
