Tylenol gave me rebound headaches real bad. I was taking Tylenol 3 times daily. I finally went to a neurologist who put me on Pamelor & helped get me off Tylenol. After that treatment, my headaches were mostly in the morning, although still chronic. They would make me cry sometimes, but they were often debilitating.
For me, applying heat to the neck helps a great deal, often keeping me from having to take any Tylenol. I still keep Tylenol handy to be used only as a last resort. I prefer to use aspirin if I have to take something.
I walk for exercise, but find that if I slack, I get headaches more often. I think walking helps relieve the tension in my shoulders.
I don't know if I still fall in the category of chronic headache sufferer, but I still get headaches more often than I used to before my surgery. I can go 3 weeks or almost a month without one of those morning headaches. Then at times I might get them 2 or 3 mornings in a row.
