I get a lot of headaches and ibuprofen has since become my best friend.
I love the way the pill feels as it goes down my throat, I love that brief respite right away because you know the pain killer is going to help out, and then when the pain goes completely away it's pretty awesome. Medicinal science for the win!
I also like Vicodin a lot. I had my first experience with it after I got my wisdom teeth out, and I still have a few left. It makes me feel happy. I use it when I have an especially bad headache or pain.
