I am currently taking Gabapentin which is generic for Neurontin. It is similar to Lyrica. I am dizzy on 400 but can tolerate 300. Maybe they can lower your dose until you get used to it.
Lyrica is very different for everyone. My friend is taking it for MS and it helps her with few side effects. When I took it I hardly could remember my name. I had a stubborn doctor, and you have to titrate off Lyrica. Do NOT just stop taking it. Slowly reduce dosage if you have to go off it. I had such a terrible time on it I can't watch the tv ads for it. As I said, that was me and it is different for everyone. Best of Luck.
