They put me on Zofran 4mg at first, which worked for a couple days and then only worked to curb some of the nausea and none of the sickness. Then they put me on something else (I forget the name sorry), 10mg of that, and that didn't curb it either. They told me take vitamin b6 at night, eat small meals and drink lots of water. All of which helped me to am extent with the nausea which started at 7 weeks but none of its curbed the vomiting. Some women just experience it worse than others, I'm 22 weeks and still get sick three to four times a week but thankfully most of the nausea is gone (and I don't take any medication for it).
I suggest trying the normal tricks, maybe invest in some of the sickness pops or the seabands, try sucking on lemons or adding them to your water. But my best advice is just to stick through it, and try your best to keep a normal diet so that you don't start to lose weight like I did
Zofran is my best friend still and I'm almost 16 weeks . Eating helps me now though, try some tea or lemon. Lemon helps me .
