End of the Week Blues . . . .

So for my workouts I always start out great on Mondays.  I'm excited for a new week, I have fresh new motivation! Tuesday hits and I'm going strong, Wednesday still good . . . then comes Thursday, & it takes everything I have to convince myself to follow through, then Friday & Saturday, and I get so busy and SO demotivated to work out.  It's the weekend, my kids are home, my routine thrown all out of wack!

 I fell off the band wagon this weekend for both diet and exercise.  I'm never going to get the results I want if I keep doing this :(

Any advice? How do get over the end of the week blues?
