I think nocturnal is a great alternative. Unfortunately, his davita center doesn't offer it and he likes the staff and doctors too much to switch.
Maybe after a month or three, you might feel like home haemo again. A break from something never did anyone any harm.
If you switch from home to in-center, be sure to say NOTHING that could be used against you in the future if you decide you want home hemo. Saying something like "it fits your current lifestyle better at this time" is probably safe, but if you say you are "overwhelmed" or "burned out" you may find that statement pops up as an obstacle when you try to get back into a home treatment program.
