MMF/Cellcept side effects

I was diagnosed with SLE four years ago and have been taking Methotrexate 25mg injection per week, prednisolone, plaquenil as well as many other meds. The steroids were starting to cause a lot of bad side effects so I was tapered down to a low dose which subsequently flared my Lupus, Sjorgens and Raynauds.

My doctor started me on Cellcept a few weeks ago and I am having serious stomach issues with it. I feel as though I have had a gastric bypass as my stomach is so inflamed and I cannot manage more than a few mouthfulls of food. In the last few days I have also started vomitting, although I feel much better after doing so. I am persisting with the cellcept as I know I have to stop my immune system working overtime.

The nurse who gave me my education before taking cellcept told me I MUST take the cellcept with food. However, I have noticed one or two people on these boards have advised otherwise.

I am also extremely tired with the cellcept and am falling asleep many times during the day.

Any advise would be gratefully received.
