muscle spasm
"I've been on these for about 8 years. They work good on low back pain, DJD  and bulging disc on my neck. Along with other pain killers it works good, but don't drive while on them. They do make you sleepy fast and also they tend to lower your blood pressure and you will get dizzy standing up. You can get a good night sleep on them. I take one 4 mg 2 times a day."
