Calories burned??? Anyone??

Oh man, Neecee... it happened again.  I had that pig out day and I'm ready to shoot myself in the face with a bazooka.  Before I did it... I weighed in at between 220 and 222.  Now I'm up to 228 in a couple of short days.  This is the most frustrating time I've had in this journey to date.  The last couple of months have been really screwing with my head. I know the body fat and water measurements on the scale may not be accurate... but I see my fluid is now up to 40% from the 34 I usually have, and the body fat % went down even more.  There's either something in what I pigged on that I'm very sensitive to, or the meds that the rheumatologist gave me are wreaking some havoc.  I hate to cut them out too..... I really want relief... but I want the weight loss more.... I'm so close to my first goal that I can almost taste it. I stuck to about 900 calories yesterday and going to try like all hell to do the "Keep it simple stupid" for a week.  I guess I just lost it for a day or two...
