Zofran

Yup...I'm one of the ones still on Zofran for nausea/vomiting.  I'm down to one 4mg pill a day, but have been taking it since week 9 and I'm now week 22. Is anyone in a similar situation? Any STMs taken it past week 25ish? I want to wean myself off, so I didn't take any today and I spent the day feeling absolutely terrible, like the worst hangover possible! I just worry about being on it for such a long time with my little guy in there depending on me...:( hyperemisis sucks!
