This past weekend I consumed 2600mg of mdma and 300 ug of LSD, followed by a few joints. I started to see people walk toward me and at one point saw a spaceship in the sky like it was real. Now, its Monday and im sober but last night I woke up from a deep sleep and hallucinated and saw spiders crawling everywhere. I also have this constant pressure on my head and on and off instances of severe dizziness and pain in my head. I have been taking ecstasy for months now and been fine but never more than one pill, this time I took 15 in one day. I haven't thrown up at all either. I'm wondering if I permanently damaged my brain or if theres anything I can do for my symptoms, thank you.
