I did not use Lyrica for BZD w/d. It was Rx'd for FMS, which I did not have, so I came off of it. It is more potent than Neurontin. It potentiates BZDs by making them "stronger," if you will.
I had a very difficult time coming off of it. I had to water taper the last 25 mg slowly, and the w/d was very similar to BZD w/d although it isn't a BZD. I have a lot of health problems, so YMMV.
It is approved for neuralgia and FMS in the US and GAD in the UK. I would just investigate it a little more before you decide to take it. It might help with some of what you are going through, but there are probably safer alternatives that could also be better adjunctives for whatever specific symptoms you are having.
