Muscle Spasm
"Honestly, it didn&#039;t noticeably work for my back and pelvic pain at first when i took the recommended 10mg dosage.  So instead of taking 10 mg, I took twenty. If you do that, it works enough to make muscle pain tolerable. I wouldn&#039;t recommend taking more than 2-2.5 of the 10mg pills unless you want to sleep though. However. You will get the best sleep possible! If you take more than 10mgs, and taking tylenol in between doses. For extreme pain and discomfort."
