LOL!!
Everything you have said Lou, is perfectly normal.... The food/hunger feeling should pass when you get into ketosis (no more than a day or 2)..
You are quite right, because of your water intake, you will be constantly peeing!! lol
Keep an eye on your bowel movements too, as this diet can often (doesn't always) cause constipation.. Just be aware hun..
You are nearly over the worst... Good luck x x x
