What's the best way to get rid of a really bad headache?

Get away from electronics, and take tylonol. Aspirin helps too. Lay down on your bed and elevate your head, prop it up with a pillow, but not too much. Drink some water if you need to. You can rest your body and your eyes or you can actually go to sleep.

I get headaches when I have not been to the bathroom in a while and that's basically the only reason I get them. So I drink room temperature water which usually sends me running to the bathroom within 10 minutes. When I'm finished, my head stops being within minutes.

Hot coffee, with the combination of paracetamol, and then just relax. I did this many times and so far all works great.

Even great, relax and get head massage. It's almost impossible for me to get headache afterwards.

Paracetamol

take aspirin and lay down on your bed in a dark and quiet place
