What will happen to me if i'm having lsd flashbacks?

Heavy bummer: If you've been clean for a long time & now have persistent flashbacks, visual phenomena like when you were trippin', & they interfere with your daily function, you may have Hallucinogen Persisting Perception Disorder (HPPD). See your doctor to rule-out neurological disorders & for referral to a psychiatrist & psychologist. Some triggers are caffeine, fatigue, stress, THC &, in some, SSRI's.
