I am also a migraine sufferer.  I have been researching medications, therapies, etc, for many years, though I am not a doctor.  I am, however, intellectually capable of becoming one and I have been correct in diagnosing myself many times because of the amount of research I have done.  I have helped a lot of people, too, by telling them to get their doctors to check them for certain things that I thought they might have.  

Anyway, any doctor who would put you on all three of those meds is over-doing it.  I hope you went off the Lyrica and Toradol, neither of which seem necessary in your case.  The diltiazem alone should help, and the others will only add to any drowsiness it may cause.  I am in the habit of getting second and often third opinions -- doctors are human and fallible, especially with people who don't fit the mold.  (I have idiosyncratic reactions -- or what you might call very different, unexpected reactions -- to medications so it is vital that I do my own research and urge doctors to start me on much lower doses and titrate up much more slowly than with the average person.)

I hope you read and listened to the answer you got here- Toradol is normally a temporary, emergency fix for migraines, not a daily usage drug.  It can also bring on renal (kidney) failure when combined with other medications or conditions as it puts the kidneys into overdrive.  I had acute renal failure from a combination including Toradol.  I hope you are off it.  I hope your migraines are better.  I am considering dilitiazem as my next choice for migraine prevention now that I am older and have begun to have bouts of hypertension.  All of the other migraine prevention meds I have tried have either had bad reactionis for me, or simply did not stop the migraines.

So, how are you?  What are you taking now?

Best Wishes,

Laura

P.S.  Do you get weather-related migraines?  Up until recently it was thought ridiculous, but other migraine sufferers I know (and now professionals believe us) will get migraines from weather fronts...usually high fronts with low fronts pushing behind them, but sometimes the opposite.  We all get them at the same time and for the same duration and find that emergency meds do not work on them at all.  I wonder if the preventive ones work.
