Will my bladder ever evolve to the point where I can make it through the weekly Zoom meeting without having to use the restroom?

Yes, your body is a learning machine and you are training it and transforming it and as more hydration gets in to the actual cells, your body is trained to uptake the water. Your frequency of going to the bathroom will decrease. But, in the meantime remember every trip to the bathroom is a fat loss opportunity and free exercise!
