I use the above over the counter sleeping remedies rather too often but find that first of all I get a good night’s rest. I take 2 x one per night tablets which knock me out almost immediately.
I’m not a doctor so can only share my personal experience but have to report that following this my movement becomes much more fluid and quicker.
The following morning most of my stiffness and slowness of movement is vastly improved. I also feel mentally sharper.
Please discuss with a qualified professional before trying this but I’d be interested to hear if anybody else reports anything similar.
