I used to suffer with crippling migraines from back as far as I can remember up until my middle teens. I used to get them at least once a week and usually more, like three times plus. Then, in my late teens and twenties they really slacked off and I would go months and months without getting one. Lately it seems I am having a recurrence, 'though.

My doctor just put me on Imigran50 yesterday. Not cheap at £6.50 per 6 pills, but if I get relief then I suppose it's worth it.

Originally, when allergy tested all those years ago, it was determined at that time that my migraines were caused - or triggered - by an allergic reaction. Unfortunately my triggers are hard to avoid: dust (try to avoid dust, just try without living in a bloody bubble), all known grass pollens, animal dander, and msg (the only one that's semi-easy to avoid - not completely easy because of EVERYTHING they put it in and add it to, dammit

).
Nothing used to give me any relief if the headache was already "full-blown". The only thing for it was to go through "the cycle": throw up, lay in a dark room and sleep, undisturbed (because if I got woken up it would hit back even harder), until waking up naturally. If I caught the evil thing at the onset and fed myself a major dose of caffiene sometimes that headed it off and stopped it from becoming severe. But, if not, I had to go through the cycle.
I thought that I had gotten a reprieve, a remission of sorts - and, I guess, for years I had. I have a feeling they are now triggered by stress more than anything else.
MeShell, I am glad you have found a miracle pill that is working for you.
