jemahon,

Have you looked into the inter-actions of combining Neurontin and Xanax (Alprazolam)? The data I found says that they can react synergistically. The sedative effects of the Xanax may be magnified by the Neurontin.

I was on Klonopin and switched to Neurontin. The Klonopin was making me too sleepy and drowsy.

Maybe you could switch to another drug for the anxiety. I take Paxil for an anxiety related disorder. My brain gets stuck looping on mundane thoughts like the words to a song or spelling of a word, etc. The Paxil allows me to break out of these looping situations or even prevent them altogether.

Benzodiazepines (Alprazolam is one) are a rough drug to take long term. Have you tried any other form of treatment? Have you had any blood work done, specifically your folate and B-12 levels? I would bet you are low in both. B vitamins are the anti-anxiety vitamins. Some people have a genetic predisposition to be low in these compounds.

Do you drink any coffee to help with the fatigue and dizziness? My doctor read me the riot act for using caffeine to combat the benzo fatigue. They work against each other.
