Return of the Nausea

Ugh!  I am so nauseated!  I woke up fine this morning, early.  The cats woke me up around 5:30 with their fighting.  I tried to go back to sleep, but was unable to.  I haven't really eaten this morning, I had some coffee and leftover cake (just a bit).  I felt fine at that time.  Then I had some massive D.  After that I started feeling nauseous.  Nothing helped.  I had another BM (D) and for about 20 seconds I felt better.  I tried to shower thinking that might help, and it did for a few minutes, but now the nausea is back.  It is the worst feeling.  I am not sure what might make it go away.  If necessary, I'll force myself to throw up, because that might help.  But I don't know that it will.  I hate this worse than pain!
