Time to Stop Baclofen?

I visited my Neuro on Tuesday, were she suggested, among other things, that I up my dosage of Baclofen since I seem to have been tolerating it so well. However, since adding one more pill per day, I have felt weak and dizzy. It suddenly struck me that baclofen could be the cause of my increasing weakness and reduced balance. I'll be back to my normal dose today, then ask the neuro how quickly to reduce the dosage to zero so as to try life without it for several months.  It'll almost certainly be a trade-off (more leg spasms, less weakness and dizziness), but going off it for a while should give me a better idea of what those trade-offs are.
