I Have Parkinson And With It I Have A Sleep

I have Parkinson and with it I have a sleep disorder where I often make loud noises and kick and fight. I emailed my Dr. about until my next visit. I do this about 4 or 5 nights a wk. I take clonazepam 1 mg. and 12 1/2 mg. of Amitriptyline HCL. at bedtime. I was going to look up the class of the durgs. My Dr. suggested that I try increasing the dosage of amitriptyline but I have difficulty with drug hang over the next. my sleep disorder is keeping my husband from getting rest. I was going to try holding the clonazepam and increase the amitriptyline. Would I have withdrawal of the clonazepam? What do you think of this plan?
