So I was told to always weigh yourself in the morning verses at night, at your heaviest and I honestly do both but what I have noticed is, I loss weight in my sleep, is this possible? Last night I weighed 263 even and this morning I weighed 261.8. Each time I weigh myself I always do it 2-3 times to make sure I'm getting the same amount and each time the scale said the same thing last night and this morning. Can someone really make sense of this for me please.

You lose water overnight - people usually pee out a fair amount of water in the morning, but we also lose water through our breath. If you've ever breathed on a pair of sunglasses to steam them up and clean them you have experienced this - think about a whole night of those steamy breaths!
