Hi, For PN I find Lyrica to be more effective than Neruontin. I take 150 at supper time and 75 at bed time. It is very expensive but I have insurance. I also take 20 mg of Baclofen because I have FMS too. I have trouble with blurred vision and I think it might be related to Lyrica. Otherwise I would probably up my dose of Lyrica because I still have some trouble falling asleep due to burning sensations in my legs.
