I was put on them for TMJ, I started at 10mg, they do help with pain and they do calm you a bit. Until you get used to them you may feel a bit dopey next morning, take them earlier if you can. I really rate them to be honest, but I am on 20mg now. Every now and then I go down to 10mg and take a sedating antihistamine to calm me and get me off to sleep. That way I keep 20mg effective.
