Muscle Spasm
"Wow, this medication makes my back pain &amp; spasms go away. The downfall of this medication is the &quot; Knockout Feeling&quot; I took 1 yesterday around 6:30 p.m., at 11:30 this morning I was driving to an appointment and felt detached. The medication works, however being tired, dopey feeling and foggy headed are the negatives for this. It is too bad it makes me so tired. My back on the other hand feels great."
