A Weigh-In - ugh

Interesting weighing this week. My weight spiked to 169+ and I didn't want to post that, but here I am. But today was a new 5 week cycle with trainer Holli, so we weighed - 166. I don't get it. When I weighed in the first time at the club, it was off from my scale by 1 or 2 pounds. Well, I guess this is just 3 pounds off - JUST! I will continue to go by my own scale - darn it. I really need to address my eating as my sleep has also been really crazy this week and I know they can just work off each other - tired, eat more sugar - eat more sugar, sleep disturbed - tired, eat more sugar, etc. That is my goal for the week - really think about what I am putting in my mouth again and get better sleep.
