Lisa didn't sleep all that well but got some energy back by noon, and went out to lunch with some family who came down from Nashville to visit.  Afterwards, she's been tired and went back to bed.  She still has some bone pain (not too bad) but she's also bothered by her heart rate which is around 110 even after laying down for awhile. We called the cancer clinic, and they suggested drinking more and not taking the Zyrtec tonight and recheck in the morning.  A heart rate of 110 isn't anything to seriously worry about, but it's still not as expected.  During the call, I found out that the immune booster shot was Neulasta. It works only on boosting white blood cell creation, so it's not intended to help at all with Lisa's slight anemia caused by the chemo.
