I suffer with CDH and migraine and have been on lots of different drugs. Ive been on Topirimate for about 6 months now and have found that it has lessoned the frequencey of my migraines. My main trigger is smells such as perfumes so I still have to avoid that but unlike other drugs I feel good on this drug.
I have got use to the pins and needles, I have a slight tremor in my hands and sometimes I lose my train of thought when I am speaking - not sure if that is the drug or just me!
In general this drug has meant that I have felt well enough to exercise again, something which I haven't done in a long time.
My advice - give it a try - begin with a small dose and build it up and think positively
