We're all different, aren't we ... gabapentin helped me, calmed my nervous system so it didn't cause so much pain, but as my nervous system continued dying I got to the limit of how much gabapentin my doctor would prescribe so he sent me to a neurologist who prefers Lyrica. The first day, it made me sleepy but it doesn't any more. I'm taking 150 milligrams twice a day but it's not working as well as gabapentin did. I took Lyrica CR for 3 months but my insurance company won't pay for it any more. It didn't work as well as gabapentin either. I will see my neurologist as soon as I can and ask what to do. Peggy
