 The limits of some of these medicines is really important because I don't want to have to deal with somebody changing their mind. Now, somebody could say, you know what, I'm tired of needles, I'm tired of taking pills, and I want to take a break. That's great. There's no problem with that at all. But what I'd like to avoid is somebody saying, you know, I don't really, you know, I want to go back. That could be a problem if somebody has some serious changes that have already happened.
