Cluster Headaches has no triggers. They attack in regular intervals. Certain foods and alcoholic drinks will make the attack periods last longer and the headaches much more intense. A headache that last 10 to 15 minutes with a beer in your system might last a few hours. Alcohol and chocolate for me can trigger an attack while in a cluster period - not while I am in remission. Alcohol is the worst. Avoid it at all cost while going through a cluster period. All kinds. Alcohol will only make things worst. Eats dry soups and teas often. Stay hydrated. Responsibly consume caffeine such as hot coffee. It helps; each individual might have to figure out how to use coffee for their own selves. A warm shower during an attack can help. Relaxation is also needed. Stress does not cause clusters; stress causes the attacks to last longer and makes it take longer for us to return to remission. If you are an anxious person pre- and post cluster periods you may be subject to panicky feelings; panic attacks. This is part it this disease. The pain is intense and during periods you have to take time to deal with your feelings so that you can expedite a return to remission. You have to remain active and have a regular sleep pattern and wind down after activities slowly - never to fast. I had not had an attack since Oct. 2021 until a little before Christmas Day 2022. I am about three weeks into a cluster period now. Sometimes I get about 8 - 10 attacks a day mainly at night and some early in morning around 9:00 am. Most lasting about 30 minutes and some lasting longer up to 3 hours. I have had these a long time, about 20 years and can share remedies that might helpful to people. Thanks for listening and have a wonderful day.
