Metaxalone
"Because Flexeril made me really drowsy I asked for an alternative and was given Metaxalone. I found that it worked just as well without the drowsiness and I was happy with it. I take it for when I throw my neck or back out. Then I started taking Viibryd (anti-depressant) two weeks ago. I checked here for interactions between it and Metaxalone and it said there was none so when I needed it for my back this morning I didn't hesitate to take one. And oh my goodness, I became super drowsy and pretty nauseous. I was also a bit unsteady on my feet. I had to climb in the bed and sleep it off."
