migraine
"I have suffered from migraines since I was twelve, but a year ago (I am 24 now), they started to get more frequent and crippling. During one particularly excruciating attack, I called my GP crying. She prescribed me sumatriptan (tablet form), and it has been great. It takes away all of the pain within an hour, even if I take it while the migraine is already past the initial stages. I do get side-effects - slight loss of sensation in my extremities, fatigue and a feeling as if there is a weight on my chest. The first time this worried me, but now I'm used to it. It's a bit uncomfortable, but so much better than going through a full-blown migraine attack."
