weight loss

Al

hey ladies! I need some tips and advise! i recently (in the last month) had surgery and since then have lost weight. I know this is normal but I go a few day's and then will just start vomiting. My doctor has prescribed me like 4 different anti-nausea meds and they work a few days and i will start vomiting again. I've tried peppermint tea,ginger ale... my question is any thing to settle my stomach for I can keep my food down!! I weighed 119 going into surgery 3 wks later at 102. Before you ask yes I have asked my doctor my surgeon and my bf(who is also a doctor) and No One knows what's wrong. I'm not pregnant and test negative for the flu. any suggestions would be helpful thanks!!
