Zofran and constipation

I am currently taking Zofran (day 3) My prescription says to take it every 4 hours. I am noticing that I am fine with the first tablet (besides constipation). When I take the second one, I am natious and have this incredible desire to not stop eating. Nothing seems to satisfy the hunger. Not to mention the incredible bloating and cramping Anyone else felt this way? Im going to go to just the one in the morning and just be sick the rest of the day once it wears off.

Zofran has not been helpful for me at all. As a matter of a fact i will still throw up after taking it. It has gave me real bad constipation which has caused bad stomach pain. It is supposidly the strongest anti nausea med out there but does not help me at all.
