A thing of the past, sadly. Oh, I have the occasional little dish of ice cream or cherry or blackberry cobbler when I go I go out to eat, but yoghurt and/or rice cakes is about it for dessert, or sometimes fruit. I have to practically starve myself to even maintain my weight, let alone lose any. I honestly don't remember the last time I had a milk shake (one of my favorite things in the world) or a donut or a nice rich dish of lasagne. I rarely even drink sweet tea anymore.
Oh no - I was thinking it couldn't possibly be a weight thing because you are so thin! Plus, it sounds like you run around so much with your work... (the stress alone would keel me over).
