Night sweats are back

It depressed me quite a bit to wake up last night with a soaked t-shirt. I had gotten my hopes up that round 7 was going to be the one that did them in.  To be honest, it makes me nervous - I don't care what the doctor says. 
But as somebody pointed out (I think it was Dad) there is a reason why I am getting at least 12 rounds of chemo. After 5 rounds the PET scan didn't show any cancer cells, but they expect there are stragglers. The last 7 rounds must be designed to get the stragglers.
Kind of freaky, though, that the night sweats came back as soon as the chemo is theoretically be out of my system. I wonder if that is any indication of how quickly the cells "reproduce".

UPDATE: I was just chatting with my Dad. Although the night sweats are disconcerting, I do need to remember that they are nothing like pre-chemo night sweats. Back in November I was sleeping with a stack of clean sheets, towels, t-shirts, and underwear next to my bed. I'd have to change everything at least 2, usually 3 times a night. So at the very least, things are much, much better. And on the thinking positive side, this night sweating I am experiencing could even be unrelated to cancer (often when we check on Emily before going to bed, she has broken out in a sweat and not awoken to kick off the comforter).
