Headaches flatten me - or the meds do

It kind of sucks having headaches. But there's not much that I can do about it that I'm not already doing. The weird thing is that when I take some meds to help, I feel... flat. Humourless. I feel not happy, sad, or anything else. Flat and just existing. What's it like exactly? I'll try to show.

Boy this headache sucks. Hey, did Laura make a joke. Yes. Okay. Now I should put my food in my mouth. She is looking for a reaction. Mention that I was funny. Wait, it wasn't supposed to be a joke. Oh. I should read a book. Laura is still talking. Not sure what about. Huh.

Not fun. I can't imagine the suckitude it would be to be on meds like that all the time. :-/
