Sugar addiction behaves similar to nicotine addiction. Do you smoke?
A couple of things happen. When you eat that "feel good drug" (sugar) in your brains releases the feel good chemical and then the chain starts. You want to keep feeling good so you keep doing what you know that makes you feel good. The thing is..... ITS A TRICK! It does NOT really make you feel good. It makes you feel bad and sick and like you failed. Then you want to feel good again so you eat more sugar! Just being able to wrap your head around what is really going on in our complex minds can help us to defend ourselves. Like I said.... first things first.... REMOVE YOURSELF OR THE BROWNIES FROM THE AREA. FILL UP ON WATER. BRUSH YOUR TEETH. Allow yourself to admit that YES, you would like to have it, but NO you will not have it. You will not be a slave to a freaking brownie. Just reaching out on here like you did is a sign of wanting to not fail. Go for a walk. Whatever it takes. Don't use the fact that you already had cheesecake to justify having a brownie. Set a goal.... Stay within your calorie range and workout routine for a week and reward yourself with ONE small low fat or healthy made brownie at the end. Give yourself something to look forward too. Now, get off the ledge!
