When I finally came across a puck of soap here, it was just as bad, a non glycerin soap and so I followed the same advice, again no luck.
I thought bugger it, it must just be the crappy soaps, so I tried it with TGQ soaps which are very very good. There was nothing thicker, creamier or slicker about the soap, with the addition of glycerin, than without.
Everybody else seems to swear by it though, so YMMV.
