Sabotage or Know Thyself?

Ok so I had a little loss last week. Only .6 lbs. so, here I am. Trying to do the elliptical a few times a week and well over the last couple of days I've lost more. 

I weighed myself on Friday and I was 193.2. I weighed myself today (Sunday) and I'm at 191.6. Hmmmm, ok. 

I'll take it but I'm not quite sure how. I've been keeping track. Drinking my water. My choices weren't that great. 

Knowing this and knowing my weigh in day is now 5 days away I have not had good choices today. Already. 

So, what is it? Do I know I'm going to have to work harder this week or did I just self sabotage?
