This is a very interesting question. My husband was diagnosed with Parkinson's recently at age 67. He worked shift work most of his life. Evening shift, night shift and sometimes different shifts during a week. His body never knew when it was time to sleep. I notice he is not sleeping good at night. Also not napping as much during the day. He has not complained about it.

police officer 17 years, almost all of it on 11pm to 7 am... loved it

I was also working many years as a night nurse

Well surprise I was looking around on YouTube and found a video
Dr Axe Magnesium Deficiency now believe it or not it is working for me I have now had 3 good nights sleep in a row which I always thought that not sleeping was being caused by the Parkinson’s But according to what’s said in the video it looks like magnesium or the lack is the answer.

Now if you go this route please check with your doctor that these magnesium tablets or liquid do not have problems with your tablets, I’m personally not on any tablets

Although I was diagnosed with Parkinson’s in 2010.

Well the magnesium tablets seem to be doing something as that’s the 2nd night I have had a good sleep in a long time slept from 8:45pm till just now 05:58 Wow thats never happened in the last 6 years.
