Maxalon is an anti-emetic (vomit) drug, not an anti-nausea one. it forces the stomach to empty into the intestine more quickly, essentially making sure you keep food down - but with MS, a lot of the problem is that your stomach is empty and you feel like crud - if you're throwing up, maxalon helps cos it helps you get food/energy - if you're just feeling horrible, it can actually make you feel worse (this was my problem) because you are sick from hunger, and then you force the food through and feel sick quickly again.
