Sorry to hear that you have this disease and the treatment you are taking is affecting your time with your family. Way back when i was first diagnosed I was started on Requip then Mirapex. Both of these drugs did very little for my PD symptoms. However, they did make me sleep. So much in fact that I completely lost 6 months before we could get them stopped. While they may be neuroprotective, I simply could not afford to sleep all the time with kids and a full time job that required me to be sharp and mentally focused. I was started on Sinemet and got my life back. That was 10 years ago. Yes, We have had to strengthen the dosage fom time to time but Sinemet still is working for me.
Reduce stess, exercise, and join a PD support group are the best pieces of advise I can give you.
