When you're sick, you obviously want to get better. You do what you think you need to and wait for whatever to pass. When it doesn't pass, the next step is pretty obvious and was the first step I took once my health insurance kicked in.
This is quite coincidental. I just purchased Cheerios this past week. I was thinking to myself as I read the label, "Wow, I didn't know they were gluten free". Well, it turns out they might have been mislabeled.
