Like Handpayhopeful said, take it one day at a time and go at the pace that is right for you. As far as Vegas, don't beat yourself up while you're on vacation. Try to make better choices but don't stress out about it. Plus, you'll get plenty of walking in while you're there. Get right back to you regular routine once you get home.

Also, I know this is only a six week challenge but try to look at it as a lifestyle. You don't want to erase all your hard work once the challenge is over. You got this!!
