Cannabis is quite effective for that. I remember last summer I took some painkillers on an emptry stomach then took the dog out for a walk. While I was walking I got hit with AWFUL nausea and was preparing to throw up. Luckily I realized there was still a packed bowl (with a lid) in my pocket, so I took 3 tokes and *poof*, nausea 100% cured. Cancer patients don't just use it because it's fun. Glad to hear you've discovered these benefits too .
