It might help to put only your right hand on the camera body and use your left hand to cradle the lens, or to put your left palm on the bottom of the camera rather than the left side. As with later AF film camera bodies, the grip on the right side of the camera body makes it easier to hold the camera body primarily with one hand, while using the left hand to steady it.
On more compact DSLRs (Nikon entry level, Olympus E-series, etc), the left side of the camera body becomes even smaller and more vestigial.
