The first time I tried to go off cold turkey, and
I experienced the most horrible withdrawal
symptoms (brain zaps, vertigo, jitters, etc.). After resuming my med schedule, I then began tapering off over several months. I've now been off for about three weeks, and even though my withdrawals haven't been nearly as bad, I still feel some vertigo and mild brain zaps.
On another forum, I've read where some people were given Topamax to help with the symptoms.
