I quit drinking alcohol for 7-8 months, I didn't smoke weed anymore at that time, lost interest in it at the beginning of depression four months before my onset. That was for the better ! I exercice regularly, and tried to sleep enough. And tried to be positive as much as I could, focusing on my general well being, do stuff I like etc. All the things I read here, and I would like to thank you Jay, you gave me some support and advice and other people too, like Visuals and K.B Fante. I was completely lost and you guys were here. Didn't change my diet so much. I didn't take any meds or supplements (was afraid of making it worse), although I was on Lorazepam before HPPD and started tapering off four months after my onset. My general anxiety disorder was getting better (thanks to therapy, relaxation, exercice) and I didn't need it anymore at this point, not because of less visuals symptoms, which remained steady for at least 6 months, and flared up regularly.
