Remember, caffeine is not just in coffee, Mt. Dew and all the common items you think of when looking for caffeine. That Excedrin has as much caffeine as a cup of coffee. Some pain relivers can also cause rebound headaches, which give you headaches as you quit taking them.
It sounds like your issue is caffeine related and good for you for getting a handle on it.
Caffeine withdrawl can cause headaches too... if the headaches come when you haven't had it for a while that might be the issue. Short term hair of the dog will help fix that, but the long term solution is to wean yourself off it, keep it occasional rather than a steady diet of it.
