I had such bad MS (no vomitting but I could not get out of bed I felt so terrible) so I went on MS pills, though even with them I still felt gross. Every 2 weeks I would skip a pill to see how I felt. Around 13 weeks I finally felt ok enough to stop taking them. I felt a bit sick for a few days but it gradually got better and I finally felt normal again (though I still had major food aversions and could only eat small meals or I'd feel rotten again). You're almost at the end of the tunnel, hang in there!
