I'm having random bouts of nausea while on Remicade, too. I've been prescribed Phenergan (sp?), but it gives me the same effect that Zofran gives you.
I'm still in undergrad but I understand what you're going through. I ended up staying at a college that's unchallenging and I don't like b/c I couldn't afford my "dream school" due to medical bills and being far away from home and my doctors. I decided not to get a PhD in my field of study like I had originally planned because I'm so tired all the time and I'm pretty sure some of my symptoms are tied to stress. Now I have no idea what I want to do, but I know I won't be intellectually challenged with whatever career I end up with. And because of fatigue and remaining symptoms, I end up zoning out in front of the TV instead of reading or writing (things I loved to do before diagnosis).
