It happens. It happened to me last night. You are doing exactly what you need to do- pick up and keep moving. It's unrealistic to expect to get there smoothly without ever having a bobble. The difference between those who succeed and those who fail is persistence.
1st goal- ONEDERLAND! Check!
2nd goal- Less than 194 (a number I've been stuck at before) CHECK!
3rd goal- Reach the 180's- haven't been there since 1999. CHECK!
4th goal- 180 which means hitting the 50 lbs. lost mark! Check!
5th goal- Switching to size goals now more than pounds goals. Goal is to make it to size 12, at whatever weight that happens. CHECK!
6th goal- Size 10! (can't even believe this is possible!)
7th goal- Size 8 and MAINTAIN!
