Reducing carbs makes your kidneys excrete more salt and, consequently more water, which is why you end up pissing more.
I had poor sleep when eating LCHF and I thought it was to do with your body missing the insulin drop from carbs in the evening, so the trigger for sleep is missed/reduced. It goes away after your body adjusts but I found it really annoying.
