You're right, a lot of us are insulin resistent too. Here is a list of IR symptoms I copied from my copy of "The Insulin Resistance Diet" by Cheryle Hart & Mary Kay Grossman. They call these 'health conditions' instead of symptoms, and some of them are not really scientific, but I think it gives you a good idea of what to look for if you suspect you may be IR. Also keep in mind, not everyone has every symptom.
* A family history of diabetes, overweight problems, abnormal cholesterol or triglycerides, heart desease or stroke
* Frequent cravings for sweet or salty, crunchy snack food
*The need to eat often or eat excessive amounts of food
* A difficult time losing weight even if you exercise or cut back on your food intake
* A problem with weight gain even when eating small portions
* Weight gain mostly around your waist
* Skin tags on your neck, chest, breasts, groin area, or underarms
* A history of irregular menstrual cycles, especially skipping months
* A history of PCOS
* High triglyceride levels
* Low HDL (the "good" type of cholesterol) levels, that is, lower than 35 mg/dl
* High LDL (the "bad" type of cholesterol) levels, that is, higher than 130mg/dl
*High or borderline high blood pressure - even during pregnancy
* The feeling that you are addicted to carbohydrates
* The feeling that you have no willpower when it comes to dieting
* Jitteriness, difficulty thinking, headaches, or nausea that goes away when you eat
* Hypoglycemia
* Afternoon fatigue
* Type II diabetes, borderline diabetes, or abnormal glucose tolerance tests - even just during pregnancy
* High uric acid or gout
* History of having blood clots in your legs, lungs, or brain
* A doctor telling you that you need to eat less in order to lose weight, yet those close to you are amazed at how little you actually eat
* The belief that you are at least 30 pounds overweight
* A Body Mass Index (BMI) of 30 or higher (and my book has a chart to figure out your BMI, but there are also websites to do this online)
* Native-American, Asian, African-American, or Hispanic ancestry
I would not assume any doctor to suggest any testing, so be prepared to ask for it yourself. Do your homework and know what you want to be tested for and how to interpret the results. For a list of tests to diagnose PCOS click on the PCOS FAQ link in my sig line and go to section 2.10.
Good luck with everything, and welcome!
