I'm only a month out but I've gotten used to it. I think the most difficult thing is probably learning to multitask drinking and doing whatever else. Otherwise it is a struggle. It was difficult post op while I was hooked up to the IV because you definitely don't feel thirsty. But make it a habit ASAP.
As far as peeing a lot... I can't help you there. I've got severe hairstylist bladder.
