When you have problems withdrawing from Lyrica it's very important to do a very slow taper. Reducing your dose by 10% every month works for most people. And when there comes a month withdrawal symptoms still break through, just increase the dose by 10% back again and you should be fine.
When you feel you are still going too fast you can stay at a certain dose for a month longer, it will only take some more time till you are there.

This taper will last about a year, but it will prevent you from going through hell.
Lyrica withdrawal can be just as bad (or even worse) as benzo withdrawal, so take it slow and take your time.

Good luck!
