ciao, I ask sorry to everybody for my incorrect englesh. I suffer from cluster buster headache from more than 30 years. I’m episodic, 4 months a year. my CH is very painful and aggressive. I can sleep max 2-3 hour a night. from about 16 years I decide to don’t use any medical treatment. in the beginnig of december when CH start I discovered the chetogenic diet. for me was really surprise. after 20 days of diet, pain was disappeared. sometimes I still have a very very light discomfort but not any pain.
