“How long can anesthesia side effects last?”

It depends on the type of anesthetic but generally speaking in your age group and your health is good, the anesthetic wears off within a short period of time ie. 1-2 hours. You may feel fatigued longer but surgery is stressful and that takes it out of you. Also, pain medicines make one sleepy. The entire stress of the procedure and worry and recovery is fatiguing. Recovery from that can take months. Women that go through pregnancy have prolonged effects without anesthesia. An example is accelerated hair loss 2-3 months post partum. The actual effects of the anesthetic medications is short-lived.
