Hi There;
Having RA for many years, I was for a while with one Dr that led research studies in Dallas. I was in several studies, though I don't know what the meds were or even if i got the med or a placebo. Studies are helpful for all of us of course in coming up with new treatments. However, I also found out that I was allergic to meds with Sulphur in them while on a study so that was good. You also usually get a check for being in a study. One study I was on was with a specific diet for three days while in the facility for the study. We could only eat from Panera bread restaurant for some reason, breakfast lunch and dinner. I could not stand the flavor or taste of their food and did not eat the three days, except for peanut butter and cracker snack at night. Lol, as soon as they let us go, I went to a steakhouse... Overall though the studies were no problem.
