I get cluster headaches. I can usually stop them before they get going if I am fast enough with a caffeine tablet, but sometimes I miss the window because I get them while sleeping. They are not extreme but often and take half a day to go. Doctor says he couldn't do better than how I am managing.

Your "get rid of migraines" session only talks about getting rid of them before they start, which I can usually do, rather than after. Would it still help? I have also looked at the hangover cure (not that I drink at all) because what I end up with is like a hangover. They don't seem like tension headaches.
