Zofran for nausea

Audrey
Have any of you Momma taken zofran or the generic while pregnant? I've been taking it for about a month now as I need it every 4-6 hours to keep anything down. I am finally 14weeks and want to slowly ween myself off of it since I've heard such bad reviews of the drug for pregnant woman. Also I know during the 2nd trimester my nausea should get better so i want to see if I can go without. But I'm super nervous to get off and end up so sick again. And I'm also nervous that baby will be affected from the medicine. Any thoughts??
