Imitrex and torture

I am 39 and have had true migraine attacks since I was a child. I say true migraine attacks because they are different then just a bad headache! The pain, throwing up, dry heaves and weird aura are "hell on earth!" I have noticed that if my headache isn't a true migraine and I take the Imitrex, the side affect are ten times worse! Reading a lot of the messages on this site makes me wonder if doctors are prescribing it for the common bad headaches! There are side effects either way but much worse if the headache is not a true migraine. My side effects have been neck pressure,sleepiness, queasiness, and very sore arm pain. But it is not worse than the migraine so I take it when needed. I do not recommend cutting this pill in half! God Bless the migraine sufferers! I know how the torture feels!
