The worst thing you can do is read about the side-effects. Those lists are medico-legal monsters, and not good clinical information. Ask you Dr. what to expect. Lyrica has a dose-dependant drowsiness effect, but it usually will go away after awhile, much like with benzos. Lyrica can be a great medication if it works, but it is expensive. A cheaper alternative that is very nearly the same thing is neurontin.
