Sometimes the benefits of taking a drug outweigh the risks. If you can't keep anything down, maybe this is one of those times. My doctor prescribed the same drug but I never took it. I looked it up on www.safefetus.com
and saw that there were POSSIBLE side effects. My m/s, though bad, was not so bad that I couldn't eat at all. So, I chose not to take it. It sounds like yours is worse though so you and your doctor should weigh the risks. I also know this drug makes you extremely tired so you are not supposed to take it when you might drive or need to be alert. Hope this helps.
