So glad the suspense is over and you now know where you stand, its been a long story! Even if its the not the diagnosis you wanted, its better than some of the things you (and we!) originally feared it could have been and as lescef says, you'll begin to relax and get back to normal now.
Its not nice being dependent on medication a life long but lots of people are (incl. Me and OH) and the side effects aren't always necessarily as bad as predicted and if its stops those awful attacks, then I'm sure it'll be better for all of you.
All the best for little Bronte, she's such a brave little girl and all the best for you too - you must have developed nerves of steel!
Keep us all posted! Sending
