Thanks for the feedback - that is very positive. I totally forgot to ask the docs today, but did remember when were in chemo and our oncology nurse said it's very common and of course will come back after treatment. She said the way it works in her mind and from what she has read is that essentially your body is working so hard to handle everything else that it has to "kind of shut down" parts that aren't as critical to life. Like sex, adn like your veins, etc. Because it still needs to expend lost of energy on things like heart and lungs...
