The reason for this may be that Lyrica is now a controlled substance, whereas gabapentin is not.

I don't understand this either, as quitting Lyrica cold-turkey can definitely cause withdrawal symptoms, including seizures in some people. This is clearly stated on the Lyrica website, NIH/Medline, and anyplace you Google: Lyrica withdrawal

Typically, the weaning-off process takes about a week, so hopefully you're past the worst of it.

The other thing I don't understand is why you haven't contacted your doctor directly, and why he hasn't advised/prescribed you help for getting through it, especially in light of his comments.
