I took it for my back when I threw it out.  Honestly, I don't remember
it being much help for my back, although it did make me nice and
sleepy.  I suppose I could see it benefiting your CP, but only time
will tell; everybody reacts to different drugs differently.  I was
taking it along with Aleve, and one or the other (both?) gave me an
allergic reaction and I had wicked bad hives.  Not looking to repeat
the experience.  :^)

As a side note, I had great luck with a cycle of Flomax.  As soon as I
stopped taking it, my symptoms returned, but for the month I was on it,
it worked well.
