Yes I do. I know it's easier for me than most, because of my set-up, but I encourage everyone to do it. You can learn a lot, in addition to protecting your health. It's one thing to talk about E and T levels, liver, lipids, etc, in an abstract sense; it's another entirely when it's your numbers, staring you in the face in black and white.
The money thing? I don't buy it. Think of the other stuff we spend freely on. And yes, I have to pay for mine, too. The labs don't know me from Adam, nor do they care that my name is the same as the ordering physician!
So take a tip from the ads, and just do it!
