Sleep study appointment could've been done be phone. They insisted that I come in to meet the doctor since I was put on a CPAP over two years ago. Last year all I had to do was call and ask for a letter (and that's all it would've taken this year, too), but NO. They needed to weigh me and check my blood pressure and in person reaffirm that I don't have any allergies other than lactose and that I love my CPAP. Seems like a lousy way to spend money at a hospital. I'm sure this visit was not less than $100.
