Need Help

I am 28 days deep into 75 hard and I have ran into an issue. My brother and I have both purchased the same 128 oz water bottle and have finished it every day up to this point. My brother started filling another water bottle that was smaller and easier to move around for work. In doing so, he discovered that our bottles aren’t actually 128oz; they are 118oz. Maybe we should have checked but I am at a little bit of a cross roads here. Do we restart or do we continue knowing we need to drink 10 more ounces?
