Earlier in the year, I had to go to an official function for work. My work involves a uniform with a button through shirt. My one existing shirt was too tight, so I ordered a larger size, and was confident because it flowed freely.
Roll on 3 months, and even the new shirt was too tight - standing up, never mind sitting down! - and held together with safety pin on the inside.
I got back on track on October 17th (hey, just realized, that's the anniversary of when I began in 2002 the drive that lost me 106lbs. spooky), knowing that I had another civic do coming up, last night.
Last night I was there in my uniformed splendour, in the new shirt - buttoned up and sitting down! woohoo!
