Hello Opa, my wife used to get terrible cluster migrains without much warning. She often explained that her vision begins to ‘close’ is the first indication of a migraine comming on. Several times she had to pull over off the road until her migraine subsided.
In the end doctors could not explain why but suspected ‘stress’ was involved. Like you she found that doctors wanted to do tests and offer pills passed on that.
I recall she also prefers Tylenol Rapid Release Gels 500mgs. It’s been at least 10 years now and I can only say that ‘exercise’ and ‘clean foods’ was enough to banish her migraines, though it took a couple of years.
