I am having a couple of problems. I've been sore. Muscle and joint sore. I am getting plenty of protein and not much exercise. So this problem could just be this old body being ticked off that I'm putting it through all of this. I suppose time will tell. I've only lost 25 pounds so far. I'm far too impatient. If I had lost 25 pounds without the surgery I'd think I moved the earth. Funny how that works.
