Trucks drivers must drug test, and I am not sure if neurontin would be an acceptable substance. It can cause some blurring of vision. It has with me, but not enough to affect my driving, which is infrequent and only for short distances.

Opiates would be out of the question for a driver, but if pain is a major issue and neurontin doesn't work, they are effective.
Neurontin can be effective for the shocks and tingling, I notice if I miss a dose, so it must be doing something.

I have read several different articles that say pain is usually severely under treated if a doctor has any idea that a patient has used drugs in the past. The puritannical idea persists that the patient deserves to suffer. Since this information (your cocaine binge) is so fundamental to your case that you must reveal it, I hope you find a doctor willing to overcome his prejudices.
