Lyrica works better than Neurontin, but scaredmom330 is right about the
weight gain. I had the same problem and had to quit taking both. I packed on the pounds and wasn't happy because I had just spent hundreds of dollars at Weight Watchers to lose 25lbs only to watch that money go down the toilet.
There are a couple other alternatives that are just as effective. One is Topamax, but you have to be at a high dose- at least 150-200mg. That is what I am at and what I take. It helps a lot.
