I guess I scared my husband Rick enough to warrant calling the docs and they all decided I needed to go to the ER to get checked out.  My heart beat was "irregular" and I had intense all over muscle twitches.   Turns out that my diarrhea was just draining me of potassium and magnesium and causing these problems.  So, after some blood tests and getting some pills to go home with, I started to feel better.  The chemo can give me bad diarrhea and it got on top of me faster than I could deal with it this time.  I'm okay now.  Just feel like a Pepto-Bizmol commercial.  I won't be going to work for a few days.  Gotta get my strength back up.
