I'm now up to 2000 mg a day, too. I had my flu shot, and am careful to stay away from sick folks, too. So far, I haven't gotten sick. But, cold and flu season is just starting. I still work half time. I've been on other immune suppressants (methotrexate, imuran) and did have some experience with illness on both of them. The worst was shingles - yuk.
I do worry about the exposure to germs. My husband and I want to take a winter vacation to Mexico in March, but I'm a little hesitant because of the cellcept. I'm going to run that one by my doctor.
