For me it was a perfect storm:
-I was increasingly frustrated with the way I felt, and how my clothes (didn't) fit
-My schedule was such that I knew I couldn't do long WW meetings, and mentally I felt like I was already pulled in too many directions to do major meal planning.
-I knew about 10 people at the hospital where I work who had gone through IP and a few had been in maintenance for more than a year
