The first full day I was off, my heart rate went up to over a hundred, and stayed there for most of the day, tapering down in the evening to a cool 80bpm. On the second full day, I had no problems at all, heart rate stayed in the 70-80 range
all day. Now, on the third day, my heart rate has gone back up. It's been around 110bpm most of the day again, and now, in the evening, is starting to taper down...right now it's about 94bpm.
