Honestly I would just tell the doc you are taking the Lyrica and then don't. Theres nothing wrong with being your own advocate. You know the drug is not working for you, then don't take it. Its another drug your liver has to try and process.

Just keep telling her it is not working for you but don't keep taking it. You should have seen some benefit after a couple weeks.
Next time you visit the doc, you really need to let her know that the drug does nothing for you. She is not listening to you on this one and that is not fair.
