Just a note of caution, too: Be careful to not take TOO much of this drug, as it can cause your muscles to be SO relaxed, they're not able to support you well. And some spasticity can be a good thing: without it, I would not be able to stand at all. I stopped taking the drug when I needed SO much to reduce the spasticity that my legs were like rubber bands, and I fell and broke my leg. I've since learned that I just may have to put up with some muscle tightness if I want to keep any mobility at all.
You really need to talk with your doctor and see if you can find a point where you're taking enough to keep comfortable but not so much as to be risky. And yes, don't just stop taking it. There are many meds that you need to taper off, not just stop "cold turkey", and baclofen is one of them.
