Hi there! Stumbled on your page and thought I'd stop to say hello! I had a similar situation happen where I lost weight on SP only to gain it back. Ugh. Seems like it was much easier to lose the first go round! It's especially frustrating being on the petite side... I'm 5'3" also and a few pounds means a higher clothing size!
Anyways I'm sure if we keep at this we will meet our goals again!
