I have an appt. the 21 at the Diamond Clinic in Chicago. I wanted to see if anyone here has been and what to expect. I am still not sure if its worth all the money. How can one Dr. help when nobody has been able to help and I've been on every med. under the sun. I just hate to spend so much money, and it not work. But, what do I have to lose?? Just wondering what your experieces were.
