Well, its been 3 days and I haven't had any follow-up headaches, so I am one grateful dude! My guess is the 3 that I had three days ago were caffeine induced from all the pop I drank... The good news is I know too much soda can trigger a headache, along with all the other pleasure foods I like!!! The longer I have them the more foods I find that I cant eat, I thought it was bad with the foods I have to watch for my arthritis, but the headaches don't even play in the same ballpark as the arthritis! It seems I can barely fart without getting a headache, lol.
