My appointments were always early in the morning but never as early at yours. At my treatment center, inpatients were scheduled first and then outpatients. I assumed the early scheduling was because anesthesia requires fasting. The long ride to and from treatment is rough, so rough that I asked to be hospitalized. They said no and it was just as well. It forced me to make an effort when I wanted to stay in bed until the next treatment. Many caretaker/drivers (our exhausted heroes and heroines) hold full time jobs and the early hours accommodated their work schedules.
