what's the best remedy for a really annoying headache?

I read somewhere that when you have a headache it doesn't mean that there's something wrong inside your head. It's the body's way of telling you that there's something wrong somewhere else in your body. What I normally do is to take a shower and wash my hair. Sometimes it could mean you're dehydrated so drink a lot of water. If you just woke up, it could be you've slept too long or you don't have enough sleep.

Sometimes massaging your temples helps. Although, it depends on how bad of a headache you have.

Other than pain meds the only other thing I do is try to lie down, even if it's just for 10 minutes and "sleep it off." It doesn't always help, but sometimes it does.
