Exhaustion is setting in.

I honestly don't know where these mythical endorphins you're supposed to get from exercise are.  I have been really irritable and grumpy lately because I'm just so bone tired.  If I were the person being accused of murder on Legally Blonde, I'd be guilty.  (Exercise gives you endorphins, and endorphins make people happy.  Happy people just don't kill their husbands.)

But I keep slogging on.  I am seeing results.  But I've lost the excitement, so even the results aren't really motivating.  But I keep on swimming.

Thursday makes a month I've been at this.  It's longer than I usually go, and definitely more consistent.  I just hope that eventually those endorphins will kick in and regular exercise will make my energy levels rise.  Until then, I'll just keep on keeping on.
