I have developed a really horrendous case of HPPD recently. I've actually had it for about a year, but recently due to heavy psychedelic use the symptoms have increased ten-fold. To be honest I'm starting to get a little freaked out and paranoid. Does anyone have enough experience with HPPD to tell me how long it takes for it to go away or at least die down? Right now it honestly feels like im waiting to come up on 2 hits of blotter. Do I need to abstain completely or just cut back for the symtoms to diminish?
