I've taken gabapentin for years for neurological issues. It helped me tremendously because it allowed me to stop taking another drug that had odious side effects. As a single med, it doesn't do much, but it sort of acts as a booster to other meds for neurological issues. For me, it was like a miracle drug.

Maybe that's why your doctor has prescribed it. It may help you as you get all the Klonopin out of your system. Klonopin can cause withdrawal symptoms that people find unpleasant and it can take quite a while to get it all out of your system because it has a long half-life. Weeks or months.

As a stand alone drug for anxiety, I don't know if gabapentin is a good choice. It's excellent as an add on drug for neurological symptoms. If you get too high a dose it can give you vertigo, dizziness and bladder spasms (feeling like you have to urinate or not knowing you have to urinate.) There's a whole list of side effects for it and vertigo and bladder spasms are the only ones I've had. Those go away if I skip a single dose (with the doctor's permission) and then take it as prescribed again.

It's possible your wired feelings and other symptoms are a direct result of coming off Klonopin, rather than a side effect of gabapentin. I don't know if gabapentin is a good choice as a stand alone drug for anxiety, but it did wonders for me when I was suffering greatly with a neurological issue. I've been taking gabapentin for close to 20 years. For me, it was a life-saver.

I hope you can work with your doctor to find the right dosage
