Minnie,
I don't know the answer to your question but I wanted to say that I am 8 mos. post treatment and still exhausted. I also have Fibromyalgia which I've had for about 4 years so I've always been tired but not like this. I had lost 50 lbs. before diagnosis and then 30 lbs. while being treated and I thought with the weight loss I'd have more energy. Not so!
