Hey all about two months ago i took my first tab of acid or what i think it was because the other guy who took it with me got no weird effects. overall nice trip yet kind of went down after the last couple of hours. I smoked weed the next day and then some weird stuff started happening. I started feeling weird as hell. I developed crazy panic attacks and derealization for three weeks. Now no more panic attacks or derealization stuff. i don't have full on visuals like my visuals are minor like i can see text moving sometimes in my computer very minor and a little bit light sensitive so the visual part i could care less about. The thing that is getting to me is my head feels weird as hell like pressure sometimes and my ears sometimes full and hurt sometimes. Also i get weird muscle feelings sometimes like shocks of energy or twitches hard to describe. It seems like my brain is over excited causing my head to hurt sometimes in different places. Maybe i am just one unlucky bastard but people have told me these are symptoms of hppd but man anyone had similar symptoms? I am really worried i fried my brain permanently.
