I've been using CPAP for eight years and got used to it the first night. All it takes is that first night of real sleep and you'll never regret having one.
I have to agree with those who mentioned the travel precautions. This is definitely a carry-on item and try to carry it yourself when checking in and out of hotels. When checking out of the Caribbean Beach at WDW, the baggage handler set mine atop our other bags and it slid off and hit the ground before we could catch it. Even with the padded travel case, the housing for the unit broke. The WDW liability coverage didn't come close to replacing it, but I was able to get a temporary repair until it could be replaced.
