It just doesn't work well for some, there is a variety of results from the TOS forum members that have tried it.
I don't recall if there was any adaptation time mentioned by the TOS members ... to see if side effects calm down or not..

I know the blurry vision was mentioned, weight gain, 1 or 2 thought their blood sugar was affected by it.{ they had no problems with blood sugar # before and even after quitting the Lyrica it was an issue}
