Hello Shakin, I do not know about your paticular medication, but paranoia is known to be a side effect of some PD meds. Could you ask your PD nurse if you have one or contact a PUK nurse by 'phoning the helpline?
I have heard tha Parkinson's is one cause of teeth grinding. Maybe this is similar to what you do.
I hope that somebody can give you a more personal reply. It's good to realise that you're not alone
welcome to the forum. I have no doubt that lots of people on this forum will be able to tell you their own experiences of paranoia. It is a known and relatively common side effect of some PD medications.
Do you have a PD specialist nurse. she will be really helpful and don't worry there are things they can do to help
