Since my car is down again, I am having to walk more.  I really don't mind, tne  weather  hasn't been that bad.  I have some really good shoes for walking.  But, an old problem happened again.  I was up walking from my nephew's house to work early one morning.  It was still dark , about 5:15.  I only had 1.2 miles to walk, mostly down hill.  I paced myself and didn't rush.  but, just about 15 minutes into walking, I noticed that even though I had on my mp3 player, sound was fading.  I turned it off and noticed I couldn't hear any other sound.  I was in  close to a feild where I could see deer eating.  I could see and hear the freeway, usually.  I noticed color was faiding too  The next thing I knew, I opened my eyes and was sitting on the ground, actually, leaning against a tree.  My bag was next to me.  It took me a moment to get up.  I checked my watch and noticed that ony about five minutes had pasted.  I felt a little shakey and was very thirsty.  I drank down amost two bottles of water and felt as if I needed to have a bowel movement.  I managaged to make it to work okay.  I took my blood pressure and found it to be 120 over 70 and my blood sugar was at 101.  The est of the day I felt kind of tired and wanted to go home and sleep.  But, I had a double shift and stil had to spend abothr night at my nephew's house.  But Monday morning, after I got off of work, I did go home and sleep off and on for the rest of the day, and most of  Tuesday.  I have had simular things happen, but not in months.  The last time, I think it was while I was at work.  this time, some one saw me pass out, but I convenced her not to tell anyone.  She didn't alert anyone, she hust stayed with me.  I was only down for about a minute that time.  I told her it was because I hadn't eaten anything that day.  I had, just like I had this time.  I have started seeing a doctor and have told her aobut this. I have had test done but they came back clear.  So, is it part of menopause or not?  Any guesses out there?
