Took a few tablets over a few days. Slept excessively. Extremel...

I was just prescribed flexeril 10mg by my dentist to stop me from grinding my teeth at night. I took one tablet before I went to bed on Monday. I missed work Tuesday & Wednesday because I was so insanely out of it & pretty much couldn't wake up. From just one pill! My mind was totally in a fog & my body felt strange, especially my legs & mouth, it was hard to talk. Now it is Thursday & I still have that foggy feeling & the numbness in my body. But this feeling went away for you, correct? I'm starting to get a little scared that it's not going to go away. I've never had anything like this happen before. Any advice?
