anyone here taken something called Pregabalin? I need two hip operations and they both cause me a lot of pain, in the hips, thigh, groin and occasionally lower back. The doc has previously given me codeine, and naproxen but both were pretty ineffective. This Pregabalin is weird. Only had one and feel like I'm in a daze, sleepy and a bit anxious. They are anti anxiety pills too apparently, think I'll cease using them!
