IPT therapy in Chicago area cost

what is a reasonable cost for antibiotic IPT IV's in Chicago area.

I was quoted at $1400 PER SESSION for Dr. L

Insulin Potentiation Therapy. where insulin is used in conjuction with the IV antibiotic. the insulin makes it bind to the receptor site of the lyme bug and kills it better. more powerful.

BUT AS FAR AS I SEE, VERY EXPENSIVE.
