Yeah I had to myself. Look under keybinds in the options, reassign "Quick Look" to some other key, or assign it to a used key, then reassign that key back to it's previous bind so QL is Unset.
Also you can turn down the mouse look and camera turn speeds. Check the Controls tab in Options, at the top. It helps a lot.
QL is a nice feature, I just can't stand the constant fast camera movements, makes me incredibly motion sick. So personally I reassigned it to Shift+Middle Mouse Button. Mouse Look at 70% and Turning to below 200%
