    • So I've been dealing with HPPD for the past few months. Visual snow, light tracers, color shifts, halos, floaters and what not. However, I have this thing which doesn't happen everyday and happens only 2-3 times a day (if it happens) : When I focus at smth or someone, I get a small black dot with basically nothing in it. It is like suddenly, a very tiny part of my eye looses vision. Happens for a second only. Anyone else has that ? EDIT: Now that I think of it, if I look at a screen, usually in the dark with the device on dim settings and close to me, I see very very small pink dots moving and floating around. Also, they move around at about 15 fps, just like a computer who can't process a video fast enough and ends up with messed up framerate. What's going on xD   Was wondering if anyone else has these weird symptoms which I could not find on the web.
    • I personally don't have experience with antipsychotics, but after having HPPD and obsessively searching stuff online for about 6 months now I can pretty confidently say don't mess around with those. Nearly everyone says its help is only very, very short term and that once you decide to go off your visuals will be unbearable. So you could either keep taking benzos, get better temporarily to the point where you develop a tolerance, and then have an insanely horrible experience tapering off them, or just not mess with it at all.
    • Hey all, been a bit since I've posted here. I've been holding up well, and even though I get the occasional DP/DR, I'm managing. I'm heading back to school real soon, and was wondering if anyone had any experience with non-stim ADD meds. Used to take Adderall, but had some really bad DP/DR the day after, and have read that in general stims are not great for HPPD. Doc just prescribed me some Intuniv ER (Guanfacine HCL ER) and said it should kick in after a couple weeks. I'm worried if I should even start taking it though, and pretty much no one has any input on non-stim ADD meds with HPPD online. If anyone's had some firsthand experience, or even some scientific basis as to why it should/shouldn't make my HPPD worse, I'd greatly appreciate it
