My 1st weight loss
Seriously, weight does wonky things the first week or two - it can go up, down or sideways. I had high dose steroids during and right after surgery due to an adrenal condition and I left the hospital weighing 11 lbs more than when I went in (all fluid).
I'd rather have gone your direction, for sure!
