Hello everyone here, I've only had HPPD for 2 (or 6, depending on how you slice it) months. I had very mild HPPD from my substance abuse which lasted and gradually worsened over a period of about 4 months. The first 4 months it was very minor and manageable, but after one particularly bad trip it got to where it is today. The visual snow I have now can be very powerful especially in dark environments, and in the dark it gets incredibly intense, and I can see sometimes intense visuals. Ive only had it really badly for about 2 months so have come here to look for help and see people who have this condition as well.
