I was going to ask: actual weight or water weight? Because I do tend to dehydrate myself in new/unfamiliar places, especially when forced to do things to someone else's schedule and without my favorite things to drink on hand.

But a week seems too long to gain it back unless you weren't measuring very often.

I'd love to track blood pressure, pulse, and weight religiously but it's hard to remember to do any more than highly irregularly, and the app I use for bp and weight can't track pulse.
