Your right about marijuana having anti-nausea properties. But you have to look outside the box. Do you care much when your stoned? Unlike when your sober thinking about the side effects of your cold. When your stoned it suppresses those thoughts those allowing you to go about normally. Just keep burning it will go away soon. I wouldn't take pills. Try making marijuana capsules.
