I've had CH attacks for more than 20 years now. Recently started again after 3 years without headaches. I found O2 stops the headache entirely in less than 10 minutes. I keep a bottle next to my bed for those attacks. Really works well and no drugs....Finally a relief.100% o2 opened up all the way, deep breathing , headache gone in less than 10 minutes EVERYTIME
