Go for it. Nipple stimulation increases prolactin, which should by itself do a lot. Hopefully that by itself causes more swelling, and sensation. The oils may have other hormonal effects, that may be increased more by prolactin. You can do massage anytime, but during sleep is when prolactin is highest. Before bed is the best time, then after waking up is another good time to do it..
