The (norm) max dose for Neurontin is 3600mg,but it depends on your Neuro at one stage I was on 4200mg.The (norm) max dose for Lyrica is 600mg but again it's up to your Neuro,I read about a guy who was on 1200mg of Lyrica and he wasn't blowing it out his butt,because I checked him out.There's no two peas in the pod alike,and like the peas,there's no two PNers alike......
