Hello @marilynsue, welcome to Mayo Connect - a great place to share your health concerns, ask questions and hear back from other Connect members on what they are doing for similar health concerns. I have no medical training or background but found some information on stopping Lyrica (pregabalin) on Mayo Clinic's website here:
http://www.mayoclinic.org/drugs-supplements/pregabalin-oral-route/precautions/drg-20067411

Here's an excerpt from the page - "Do not suddenly stop taking pregabalin without checking first with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely. Stopping the medicine suddenly may cause seizures or side effects such as dizziness, diarrhea, nausea, headaches, vomiting, irritability, trouble with sleeping, nightmares, or tingling feelings."

Have you talked with your doctor on stopping Lyrica? Normally they have you taper off of the drug to let the body adjust. Hopefully other Connect members can join the discussion and share their experience.

John
