Thank you for your replies, yakedar and topgeek.
I will have to start taking the CoQ10 with dinner to ensure proper absorption. This is easily done and might reduce the muscle cramping.
I go for physiotherapy to help with the muscle aches and pain. The frequent muscle spasms prevent me from doing some of the exercises properly. At times I jump right off the treatment table.

Even though it helps, the physio is not a long-term solution.
I came across the carnitine connection when reading about the ways to counter the effect of cholesterol medication on the muscles. Of course, there are other causes of muscle aches and cramping as well. I just want to have all bases covered.

I think I'll stick with the CoQ10 for now and take it early in the evening.
