Fatigue

I had lunch last week with a friend who is pregnant and we were talking about how annoying it is when you know that what you are feeling is out of your control, but you feel it anyway.  Like when you get irritable after heat exhaustion (where this conversation started), and you know that irritability is a symptom of heat exhaustion, but you just feel irritable anyway.  You can imagine that my pregnant friend had much to add on this topic.

Anyway, today I had to get a Tdap vaccination for immigration purposes (just go with it, the background isn't really relevant for this story).  From what I have read online, one in four people develops fatigue from a Tdap vaccination.  I felt completely lethargic today, which is why I looked this up.

Do you know what doesn't go well together?  Fatigue and exercise. 

I tried to do 5 miles today.  I couldn't.  I felt achy and tired all over (and I don't think that I can blame CrossFit this time, although yesterday's workout was pretty challenging).  Then when I got to about 3 miles, I just felt....off.  And I decided that in the wake of the heat exhaustion awfulness that feeling off was the cue to stop running.  Also, another side effect, nausea, was starting to chime in too.

The really annoying part is that the weather was nice.  Quite nice.  Lower humidity than normal (okay, not perfect) and not dreadfully hot.  But I couldn't take advantage of it liked I wanted to.

My new plan is to do another 3 miles on Saturday instead.  It's not the same, but I really was not feeling okay tonight.  And now I am irritated, but I can't blame heat exhaustion.
