Hi Roy ~ I'm glad you're having a MRI. I wish ALL of us having seizures would have one. Mine saved my life.
And about Keppra .... all the AEDs effect each of us so very differently. Keppra did not bother me at all..... but I never took it alone either. I always took two (at least two) AEDs together. Right now I'm on Trileptal and Topamax and doing OK.

Here's wishing you well with the CT and MRI. Please let us know the results as soon as you get them. I've said a prayer for you and here's a hug
