Baclofen and incontinence

Hi all, have been taking Baclofen for over 1yr, but lately my bladder has been getting worse, to the point where i have been given incontinance pads that are more like nappies, i was going approx every 2 hrs and needed to be close to a loo, i decided to stop taking Baclofen and my bladder is almost back to normal and so is my sleep, i was only getting about 2-3hrs sleep due to bladder, has anyone else had problems with baclofen/bladder, i know it can cause trouble, but as i had been on the same dose for so long with no probs, i was suprised to get this happening.
