It's technically two downers, that work on different systems. So what Mr. Eyes said.
People react differently on gabapentin, I assume they do with pregabalin/Lyrica too, so I wouldn't mix them if it's your first time with pregabalin. I mean, some people get knocked out at 300mg gabapentin, and the buzz I look for doesn't get going until 1800mg. You might be one of those sensitive types. And even if you're the type that feels amped by it, it still makes you stupid, and that's additive with any benzo.
