I usually try to disguise my tics as different movements. Like, if my shoulder needs to tic, I will pretend I am stretching, or reaching for something. If my eye needs to tic, I will pretend to rub it to hide the blinking. I also try to do most of my ticcing when no one is around (like right after I turn the corner in the hallway or something).
Sometimes if I am ticcing really badly, if I focus on completely relaxing the muscles involved, it helps a little bit to relieve the need, which sounds sort of similar to what your doctor suggested (which I guess is not helping you). It definitely doesn't make the need go away, but it can take the edge off when I am constantly ticcing.
