Watch a lot of comedy. Laughing releases endorphins. People who laugh a lot during their course of treatment seem to do better than those who don't.
Ginger is very effective at reducing nausea and should not interfere with nor interact with any of your medications, but check with your real doctor. Any form of ginger; ginger tea, ginger drink, ginger candy, or preserved or fresh ginger.
