It would be nice to have someone with you. I don't know what chemo, but most weaken you, some cause neuropathy, anemia, and side effects can occur from day one. From mid treatment last bout, I had to use a walker, and buy a shower seat when I I stayed at hope lodge. There 95% or more had a caretaker with them, some even had friends or family switch out every week, and they were there for months. I always went alone to every treatment, Dr visit, test. It's not easy, and even lost my wallet once, stuck with no money, all my documents inside, SS, medicare card, drivers license, and a kind nurse lent me $20, then had to go to the bank. I'll never forget that day.
Good luck.
There may be an organization like American Cancer Society, that may have volunteer drivers to take to treatmnts. but don't know if they stay with you?
