Thank you, both!  This is a truly wonderful site and you've both been so amazing to me!  I'm so thankful for what you're doing here!  I've been seeing a Neurologist who is the Migraine specialist at Mid-America Neuroscience Institute in Lenexa, Ks since Sept. 2009.  It's been a long 6 months! I was basically born with Migraines, got my first medical diagnosis at the age of 7.  They used to be frequent but with times of no pain.  However, on the Saturday after Thanksgiving 2008 they changed big time and I've had a headache that hovers at a pain level of 7 only to spike to a 10 often daily. I was hospitalized that day and released 2 days later.  At first they were looking for stroke but then decided it was Benign Positional Vertigo with Migraine. Later they decided it was Central Vestibular Dysfunction with Migraine.  They tried Topomax but the reaction was too severe and sent me to Physical Therapy which didn't help anything.  All of this was being handled by the Hospital Neurology and ENT departments. So, then I switched to my current one mentioned above.  We've basically been trying various drug combos for the last 6 months.  Our relationship has been odd and not entirely comfy so I began to distrust the treatment plan recently after trying to many failed drugs and having so much pain all the time with no relief so at my most recent visit I asked him why my Migraines are like this now and he said they just changed and that I was not alone and my case is actually 'typically boring', said not to worry that we'd eventually find the right combo.  I'm not sure if I feel any better about it after that.  I'm not the person I used to be now and I truly feel I've lost cognitive abilities.  It's been a painful & long 16 months, I'm confused and at my witts end.  That is why I asked my question; I'd never heard of Migraines changing this way.  I've been reading your book as well.
