Hi Heather - below are some links that you may find helpful: www.sparkpeople.com/resource/nutrition_art
You say that "It's like a crazy high that I can't explain. It makes me feel like a drug addict, which I am not, but ...."
Perhaps you are addicted to food?
If the binging continues and the various tips in the articles, and any others you may receive on the message boards doesn't help you much, then it would be beneficial for you to talk with your Dr and ask for a referral to a Therapist who deals with Eating issues.
When you say you are pretty much 'gluten free' do you have a gluten intolerance? If not, then it may be that you would be better continuing with whole-grains which also include gluten, because otherwise you could be missing out on some really good nutrients. It may be that if you continue with very little gluten-containing food, that you might benefit from an appointment with a Registered Dietitian to ensure that you are getting the nutrients you require. Your Dr will be able to refer you to one.
Make sure that you start your day with a good, healthy breakfast and one that is filling, and contains filling carbs and protein. Including a piece of fruit will help you to stay fuller for longer. Having this type of breakfast, can help set us up for a healthier day and evening, than grabbing anything on the go, throughout the day. Also make sure that you are eating enough during the day. A lot of people under-eat, and don't understand that this will often cause them to pig-out later in the evening.
