Well, I went to the doc for the glucose test results
I don't think you are nuts...far from it.
Actually, I agree with the doctor. Even if you have IR, you are successfully treating with your diet and exercise, so you should be happy that you either don't have it or are succesfully treating it. But instead, you want to take a medication to treat something that you either don't have or is already being successfully treated -- i.e. it sounds like you are misusing a prescription medication.
There's a difference between something "masking the symptoms" of a condition and the condition being successfully treated. If the symtoms are being masked, there's still an underlying problem that needs to be treated. It doesn't work that way with IR -- if your insulin is fine, it's fine. You aren't masking the symptoms, your disease (to the extent you have one) is under control and doesn't need further treatment.
It's like if someone has high cholesterol -- if they get it down with diet and exercise, it's under control and they don't need medication. It's not masking the symptoms, the problem is under control. Normal cholesterol is normal cholesterol, it doesn't matter to the body if its normal because of genetics, diet, whatever. The point is, it's normal.
It's the same with type 2 diabetes/insulin resistance, if the insulin is normal, it's normal. It doesn't matter whether the person has their type 2 diabetes under control or whether they never had it in the first place.
The doctor should not have ethically prescribed a drug intended to treat insulin resistance as a weight loss drug.
For Jen and Jean -
i don't think you are being vain but i do think you are misunderstanding the situation. you say you think you still have a need for the medication, but what are you basing that on? your doctor has told you that you don't need it. there is no logical reason why you'd need it if your test results were negative. it's not a matter of "ignoring" it and ending up with diabetes down the road -- it doesn't work like that. if your insulin is normal, it's normal. taking medication is not going to prevent something from happening down the road, it's just taking medication for literally no reason. if you are worried that you might develop diabetes, you can check it again in a year to see if it's still being controlled by your lifestyle or whether you need to start thinking about medication. but if you take it now, you are taking a medication you don't need, and subjecting yourself to whatever the side effects of the medication are for no reason.
i'm the last person in the world to suggest that people blindly trust their doctors, but i also don't think people should completely ignore their doctors and decide that they need a medication based solely on their own uninformed, unsupported
