Diabetes and electric shocks in feet and legs

Patient: My sister has type II diabetes. She quit her meds and lost 100 pounds. Her sugar was still high so she is back on her insulin. She now has neuropathy and constant electric shocks in feet and legs. The meds she is on for neuropathy make her tired so she won’t take it because she has to work. How can she slow down the electric shocks. Oh and she is a smoker also. She is on pain medication but again it makes her tired.
