53 years old and very athletic, 7 days post op CoolSculpting on abs and still experiencing exhaustion?

I am 53 years old almost 54, athletic. I had coolsculpting done over three days on my lower, middle, and upper abs (2 pads each). This was for stubborn fat. It is day 7 today and I am still in pain. Numb. Somewhat nauseous. Some bruising. Unable to exercise and most important, I feel really really exhausted and often sleep up to three hours a day. I eat well. Always have. Was exercising 5 days a week prior to this.
