Am I safe to assume this stuff has no abuse potential? No euphoria?

It actually can feel nice, its Schedule 5 so not as good as other stuff but IMO its almost as good as benzos. Esp. if you take 600-1000 mg, you'll feel it for a while and might even get some opiate-like nods. Not a whole lot of euphoria though, but really nice antianxiety effects. It takes about an hour an a half to start working and you might get a mild headache at first, but it feels a lot like Klonopin or a less-euphoric benzolike effect, and lasts like half the day.

quoted from pregabalin main vault page on erowid:

A small number of users (~4%) report euphoria after use, which led to its control in the U.S.

Actually as stupid as it is. I found a bottle of it sitting at my house and took about 500 mgs. It doesnt really produce any euphoria, but its does have some anti anxiety properties somewhat similar to benzos.
