Woke up pretty much feeling like crap.  Stomach and intestinal distress.  Could be the stir fry veges I had at the mall food court yesterday.  Could be the Nexium, sometimes I think it does that.  I did get out for my walk.  Finally felt confident to get away from the smallest room in the house.  I did 5 miles, even though I didn't think I could.  Everytime I could have taken a short cut, I just thought, no, not yet.  And then I was home the long way.  I think there is something to the endorphine thing.  I still pretty much feel like crap, except I no longer care.  It is much cooler today, but still really humid and overcast.  But at least the breeze is cool.  Yesterday, every time the wind would blow, it was like opening an oven door and getting a hot blast.
