I asked this question in the "Nutrition and Supplement" thread - see here:

I've also since found it at one place behind the counter - very pricey. My doctor did say the Carnitine is available by prescription, but I will only consider that later on if I begin to stall.

It just became a matter of sheer stubborness to find it, since it's talked about so much!
