I’m on a diet and I weigh myself every morning. Last night I weighed myself before bed. This morning, I weighed myself when I got up. I was 5 pounds lighter this morning than I was last night. I was a bit heavier than usual because I had had a friend over and we ate a bunch of pizza and I always drink a lot of water.
In that time all I did was sleep. I didn’t use the washroom to pee or poo or anything else that involves stuff coming out of me.
Where the hell did all of that weight go? I understand that you sweat, but 5 pounds in 9 hours? That seems crazy.

You lose 290g of carbon in an evening as a full grown man with reasonable athlete ability. This is exhaled as CO2.
A large part of it (~3lbs) is probably the scale. Most of those digital floor scales are not accurate they try to hide this. If you get off the scale and then get back on, if it is within a couple pounds, it will just show you the same weight. Try this experiment get off the scale and then pick up something that weighs about 1lb. Get back on and it will just show you the previous weight.
You almost certainly lost that amount of weight from urinating more than usual. This can happen if you cut a significant amount of calories or carbohydrates quickly from your diet. Your body is forced to use stored glycogen to fuel itself. Glycogen is connected to water molecules in your body so when the stored glycogen is used the water is released.
I would not weigh yourself every day, because you aren’t going to notice a difference. Try do it once a week. Your body weight can fluctuate massively throughout 24 hours, like with how much water you drink, so it seems counterintuitive to weigh everyday.
Others have answered you… but great work! Don’t worry too much about the number on the scale… just focus on process… only way to lose weight is to eat less calories than you burn in a day… and it’s much easier to eat less than it is to burn more!
I’m proud of you! Keep grinding.
Over 9 hours of sleep you would breathe out about 0.75lb of CO2, breathe out 0.5lb of water vapor, and sweat out another 0.75lbs of water. That’s about 2lbs a night normally.
There could be other differences like what you wore, but it could also be error in the scale reading; cheap bathroom scales aren’t super accurate so if the house is colder in the morning than before bed that could change how it reads by a lb or two
