It's nice to know there's a reason

So I went this afternoon for my weekly chemo visit. They always ask how I'm doing. I tell them it's been a rough week physically, I've been tired....yadda, yadda, yadda. My lab work comes back & my nurse Amy (she's great & I ask for her every week) comes over & says "Yeah I bet you're tired, your Hemoglobin level is pretty low". Hemoglobin is what carries oxygen throughout your body. It's nothing serious & it should slowly start coming back up again. It's just nice to know there's a reason & it's not just in my head! I wonder if Vegas has an Oxygen Bar????
