Hello btrflynana,
It's a lot to deal with, and putting together a support system sounds great, I'd like to hear more.
I recognize a lot of your symptoms, but don't really know where to start with any input.
But here goes;
When first diagnosed (2003) I experienced reduced arm swing, very painful spasms in left shoulder, tremor (but not too troubling) and exhaustion. After delaying taking any medication for a long time I eventually started taking Requip and, like you, suffered with terrible nausea. I persevered for 6 months (far too long) but gave up and was switched to Mirapexin. I still experienced nausea for a short while (about a month) but it got better and I rarely need the domperidone for nausea now. Of course I don't know the best course of action for you - I can only tell you of my experience. Mirapexin does make me feel "drunk" at certain times but I know it passes and am grateful for the relief it gives overall. My shoulder doesn't have nearly as many spasms, and when they do occur I am able to take dizepam as a muscle relaxant.
As regards vision, yes I have noticed a difference, but this may be due to age. My vision is deteriorating although it was very good prior to diagnosis. However it is variable - there are some mornings when I don't need glasses to read, and others when I can't see a thing without them. It does deteriorate through the day, and I have noticed it is very much affected by fatigue.
I hope you get other input that may be helpful, and wish you well,
