Hi Casey, I know your question was directed to the OP, but I wanted to comment because I was in the same situation. Wanted to lose 15, lost about 9, then plateaued. I hung there for three weeks, then started to lose again. Changing up your exercise routine or calorie cycling might help, as your body gets used to a routine and becomes more efficient. Hang in there; it will happen!
