Force yourself. That is something that not many people do but if you are going to work long term then you should be forcing yourself. You are having trouble waking up early? Force yourself to wake up early, too early if you have to, that way you will go to bed early as well, having trouble finding food to eat, or can't decide? Force yourself to eat healthy, having trouble exercising? Force yourself to do it.

If you keep doing these for a couple of weeks in a row every day, it is going to become your regular day and it won't really take that much time neither and rest of the time you could relax. I have been working remote for so long and never been happier in my life.
