I don't know if posting about every HPPD experience I am experiencing is bad for my HPPD but it seems to be getting worse or new symptoms show up, I been back from Hawaii for a few days now and since then, I have been seeing colors at night, been feeling nothing but anger and severe depression, lethargic, bad chest pains, panic attacks and severe brain fog. This could be due to me taking 400mg+ of diphenhydramine 3 nights in a row on 4th of July and the nights following but this just recently got very bad.
