This happened to me too but came back in full force 2 days later....maybe you are done with nausea but it may be back. I would try to to enjoy the break while you can . I know it's easier said than done though
My MS has changed by the week and by the day. It showed up at 6 weeks, was bad in the morning, then at 7 weeks changed to evenings, and now at 8 weeks it's only if I have eaten dinner. And then there are some days when I feel totally fine all day. Enjoy not having it today! Who knows what it will do tomorrow.
