Hi, I take flexeril 10mg prn also tho it knocks me out and I'm in such pain, I right now take it every night. Its actually a good sleep med for many because its not addictive. I am not aware of any dangers with the med itself except the usual don't drive.

If you take it 3x/day and drive, you can still fall under driving under the influence. Just be careful because it does affect your cognition.
