Hi @jimmy370 I dread the day for the awful headaches. Mine is due to the AVM. It occurred in my cerebellum. At first I was getting the headaches 2-3 times per week but now have decreased to 1-2 times per month. I had tried coffee for the caffeine as my neurologist had suggested. He alao prescribed a pain medication but I refused. Instead I tried Tylenol but that didn’t work either. For a while I used a bag of ice on my head which decreased the intensity enough for me to be able to sleep. I later discovered an herbal tea(no caffeine) which helped me tremendously to the point where I no longer needed the ice. It was suggested by a Mayo Connect member. The tea is available through Amazon. For me it either takes the headache completely away or decreases the intensity to make it bearable. I believe the trick is to drink the tea when the headache starts to come on.
