Finally, 4 months and 2 days and 33.4 lbs later, one of my co-workers asked if I had lost weight and was complimentary about the progress I've made.
I know I can't be doing this just for others to notice, but I have to admit it was getting frustrating to not get any kind of recognition or feedback. For a while I thought it was because I was still wearing all the same clothes, but I have broken out a lot of clothing lately that I hadn't worn in a long time and I think that finally did the trick.
