Oh, the dreaded constipation issues from Zofran....gotta love it.
I try to walk around a lot as much as I can without throwing up, in the morning after I wake up and eat something. Also drinking apple juice which is helping me. The main thing is liquids, which I am sure anyone on Zofran has trouble drinking anyway, and water is yucky yucky, so if you can find something you can drink, drink up. My doctor says as a last result an enema works wonders. I havent gotten that desperate yet.
My mom swears by rubbing your belly clockwise about 25 times helps move things along. It works....sometimes.
