I found this cure on accident by going through this.
Two years ago I had a bad tooth. Upper right, back side. I dealt with the bad tooth for about 6 months, having toothaches periodically during that time. Over the six months the tooth gradually got worse and the tooth ache started turning into bad headaches on the right side of my head. I had the tooth pulled, it had to be surgically removed. To my disbelief I would still get these headaches on the right side of my head after drinking a beer, a Coke, or a glass of tea. These were sudden bad headaches where all you can do is sit still and stand the pain and they would only last 20 to 30 minutes. I noticed I was getting these headaches after drinking a sugary drink or alcohol beer. I put up with the headaches for another year-and-a-half. One A Day sometimes, sometimes two.
Okay here's the Cure part. Come to find out the dentist that did my surgery didn't close up the hole good enough. So what's causing the headaches for me and probably a lot of y'all is actually tooth and mouth related. Sugar and our alcohol going up through the gum to the nasal canal affecting nerves, that's where your headaches are coming from. After having surgery redone on the tooth at the dentist pulled I don't get the headaches anymore especially after drinking sugar or alcohol or anytime. So all of you suffering migraines, Custer, right side left side headaches go to the dentist and get all your teeth fixed especially the upper ones wear your roots go into your nasal Canal or close to it. You will be amazed. I hope this helps a lot of y'all.
