Anyone taken prescriptions for "all- day sickness"?

For the past few weeks, my nausea has been riddiculous. I've lost weight, can't take my prenatals, and worst of all, I haven't been able to get any quality time with my 3 year old. I tried every natural remedy I could find but nothing worked. I can deal with a lot but explaining over and over that "mommy can't play" is breaking my heart. I called my doc and they're writing me a prescription tomorrow. Anyone had any experience taking meds for nausea? Just curious what to expect.
