 So, but the metformin was not a silver bullet, doctor? No. No. There's no silver bullet. No, okay. So talk about how that's coupled with the rest of the program. When you come through and you sit down, you fill out the paperwork, you go through all those little questionnaires, okay, and you do all of that stuff. And then you go in, you sit down with Lisa, and then you go in and talk to Alex. You've got two different, you're dealing with your nutritionist, okay, and you set up a plan. My plan is I meet twice a month.
