On the drive side, it should be counter-clockwise to remove.

Sometimes, a long piece of pipe shoved onto the end of the bottom bracket wrench is necessary to provide enough force.

I'd take it to the LBS if you are stuck. They usually have a special "persuader" tool to get that sucker off.

Or, you can relive what I went through on my Fuso. LINK
Hacksaw, dremel tool, several long screwdrivers and much colorful language was required.
