Hi Ninja61, Being diagnosed myself I actually went through the terrible side effects of the nausea and dramatic tiredness that came on suddenly. Being a full time carer for my disabled daughter this was unacceptable to me so went back to my GP after talking to the Parkinson's nurse,, and requested being put on the slow release version.
Since being on that and, despite my daily dose being increased twice those symptoms have gone and I have no problems like before.
If I have the odd bad 'parkie day; I can get nauseous but one dopamine tablet sorts that out. I do get tired in the evenings and can doze off but only lightly and its probably due to my greatly disturbed sleep pattern.
I would remember we are all individuals and we can react in different ways to the disease and the medication. I would urge you to become proactive and speak to your Parkinson nurse ad then your gp or consultant.
Merry Christmas to you and yours.
