I take Neurontin /Gabapentin (600mg) 3 times a day, it has lesser side effects than Lyrica.
Lyrica is stronger, works better but makes you more foggy, very hard to concentrate etc, makes you gain weight. I just switched from Lyrica back to Neurontin.

My biggest side effect for (getting off) lyrica is unbearable itching and a fine rash which I still have some after 3 weeks of getting off lyrica. Some depression too in the beginning from getting off Lyrica.
They are both made by Pfizer. So they are kind of parallel.

Biggest advice is don't stop doing any therapy or stretches or whatever you do when you start taking these meds. It's like a honeymoon initially then you start needing bigger doses of the same med. And if you stop doing any of your therapy or abdominal breathing you get into a lot of pain. Hope that helps!
I have to take Neurontin bec it helps me do my therapy, keeps me more flexible and also helps me sleep well.
