|I thrash from side to side, try to shake this devilish limpet out,
This throbbing rhythm, now part of me, almost like a friend,
It helps to focus on the metronome, the beat changes as the bout
Crescendos agonisingly, towards it's, sweet and bitter end.
I've never read a poem about a migraine before. I've heard it's a miserable experience, and found that there is either a wide range of severity or the term is grossly overused. The imagery you use is sad, but shows a bit of optimism as well. I certainly, however, can understand how you feel like the benefits are not worth the cost. Well done and Write On!
