Lyrica works well for me. I've been told now by a few doctors that in general the dose needs to be much higher than the one you were taking for it to work well. I was recently told that it works much better at 600mg a day than at 300. I had cognitive problems with too much Neurontin but I haven't reached that large a dose of Lyrica yet and I haven't experienced any brain fog. It does help significantly with my nerve pain. I do have the cravings and want to lose weight but I also want to have less nerve pain.
