You dont have to be firm just honest 102 and with your BMI meeting criteria if you have any other co morbidities like I listed on your other thread then point this out to them also tell them how being obese affects your life, and if you have tried everything, I hadnt tried tablets, so had to do that before GP applied for funding, but I had done every diet imaginable, been to WW, SW, lighter life, joined gym, etc ;etc but could not maintain weight loss for any length of time
