I take Neurontin too
I also take Neurontin but they had to also add another pill to help with the nerve pain. Both at first have been sedating but the Neurontin I barely feel anything from it now! It takes a few weeks to get into your system!
SSDI! It varies on your condition. Some people get approved right away and others get a hard time! Since you have your doctor backing you up, you might be okay! Good luck TJay! Wishing you my best! Hugs
