I have to say...on the off chance you don't get the meds...to be off all meds for 4 years is nuts and not smart. Then what if you develop the anitbodies to Remi within the 4 years. Are you alll of a sudden off the study.
I don't know just what they are trying to prove with the study but it seems weird and it isn't something I would do, especially right after surgery. Be smart, stick to your meds and make your health the priority.
