I took them so I could relax my muscles enough so I could sleep. They helped prevent muscle spasms and cramps at night. But after taking them for about a month I started having bowel problems, as in the medication relaxed the wrong muscles, and the lack of control in this area became a big problem. I was only on a very low dose at 10mg, and so I had to quit using the pills all together. But if someone is having lots of muscle pain it might be helpful using the pills. To solve my sleeping problem I bought a feather-stuffed bedpad, which keeps me warm and softens the bed so I can sleep and wake up without pain.
