Absolutely not. I needed my strength to heal. I was too sick from anesthesia (everyone in my family gets really sick from it) for the first 48 hours to keep anything down, but after that, I enjoyed lots of good, albeit healthy, food. It was one full week before I felt human again, two weeks before I could go back to work part-time, three weeks before I could go back to work full-time, and four weeks until I could get through a 75-minute hot yoga class. Fasting would never have been an option for me unless I planned to remain in a percocet-like coma for a month. You won’t be able to take any pain meds on an empty stomach either.
