That's why I haven't taken it. I'm probably a guy who should. Overweight, with kidney disease person who, if I became diabetic, it would probably kill me.
I'm not, someone who doesn't really need it. For example, some average weight housewife who just wants to fit in a dress a little better.
And still, I won't use it even though I can afford it cause it's the long term consequences are not entirely understood.
