After 50 years I am still having cluster headaches usually 1 to 3 years apart. This time, about 2 weeks ago, I started feeling really nauseous when I woke up and periodically throughout the day. Also have shadow throughout the day. I did mushrooms twice and will try again this week. Anyone else have this pattern? For the first time I am sticking with mushrooms and no other meds. Advice to keep the cluster from blooming into full scale terror?
