HELP - HYPEREMESIS GRAVIDARUM

Hello Sisters, I really need advise and help as my doctor doesn’t really wants to help me as much as I want. I am currently 33weeks pregnant and I was diagnosed with HG early on in my pregnancy while in California and my doctor there put me on Diclegis which has been on great help . I recently moved to Atlanta and my new doctor wants me to stop taking it without giving me any options or alternatives. I have tried stopping it and each time I throw up close to 20 times a day and end up in the ER. I try to make her see that I Need this drug as I can’t eat or drink but she doesn’t want to hear me. Please what should I do , has any one used diclegis for their whole pregnancy with no side effects and does any one know any natural ways to help with HG .
