Beach Weekend=minor setback

Nik and I had a wonderful weekend at the beach!  The only problem is that my cheat day turned into a cheat weekend:/  We are almost 3 weeks in and I must say, I'm bummed about my weight loss.  I'm not losing as much as I had hoped to.  I think my body is very comfortable with where it is right now.  I have not taken measurments though so I may be losing inches (hopefully).  I'm back to business tomorrow and this coming week.  I really need/want to start working out.  I'm thinking I'm going to start up my Universal membership either this week or next week.
