LSD induced Headaches

Here is my post from a month ago: https://www.reddit.com/r/Drugs/comments/4e8wxm/permanent_lsd_damage/

Basically, I have experience with shrooms, but when I did LSD for the first time, it borderline ruined me. The guys I tripped with are drug connoisseurs, they trip LSD probably 12 times a year. I trusted them when they believed it to be real LSD. I took one tab that was supposidly double strength, and had a great night. The next day, I woke up with a headache. Almost 5 months have gone by now, and I still have narly headaches. These take place on the back crown of my head, which is the parietal lobe, associated with perception. My friend tried to convince me its muscular, and I began a routine of stretching my neck and scalp to no avail. To me, its clear that it is my brain. I definitely feel like I am fried, and have forever restructured my brain.

Does anyone else have experience with LSD giving them bad long term headaches? Has anyone felt like LSD restructured them, and after mental training they were able to get proper brain function again?
