Hey Lance,
If your pee is clear and it doesn't smell bad you are probably fine and your body just adjusting to your new intake. I think someone would need to drink a LOT more water for the water to cause a problem.
I drink 2-3L of water daily and it's normal for me. I don't have any troubles. I do usually have to use the restroom about 45m after drinking a lot of water, but I've never had any problem as a result.
If I were to start to get headaches, and/or pain, and or feel thirsty even though I was drinking a ton of water etc then I might be more concerned. But if I felt otherwise normal, and my only symptom is that I was drinking more water and going pee more I wouldn't worry.
Good news is that this morning I got a nice surprise and weighed 186.2lb!
