I have only been taking neurontin for 5 days. I have been so dizzy and clumsy and tired. I take 100mg 3 X a day. i am so loopy, cant think, cant concentrate. Heck i cant hardly remember this past week at all and have went to 2 very important doc appt that i dont really remember. Are these normal side effects? When should i call the doc? Will these symptoms go away soon? I am a light weight with pills and have a lot of adverse side effects from a lot of different drugs. I feel pretty messed up and am not sure if it is all normal. My doc pprescribed this for joint and nerve pain. Every joint in my body hurts. Not sure what to do.
