Just joined clusterheadachesDOTcom the other day and found this site today. 10 years I've had these lovely headaches. I'm currently on the end of week 4, and woke up to headache number 58 this morning. Nice way to start a day off, lol.
Anyways, I've heard of the psilocibin treatments before. I had a friend who was a test subject at University of Calgary for this type of treatment. (He doesn't suffer from the headaches, but went in and took a fair amount of mushrooms and once he started feeling them in the sensory-deprived room, got put into EEG gear). He gave some to me last week, I took a bit. Not enough to go all crazy or anything, but I could feel them. Think I might have another go at them today. Got nothing to lose at this point.
