First, welcome to MedHelp and the WL&D community. We're so pleased to have you here and congratulate you sharing your journey and posting your question.
Can see you've already met Barb who is a wealth of knowledge. Would encourage you to implement both the weight and exercise trackers. You need not record your weight if it is a trigger for your previous bulimia, however, there is a place to record your measurements, which is a good indicator as to the changes happening with your body.
Medications for other conditions can indeed affect our appetite and energy levels. That said, there are some things we can do. For instance, if your appetite is soaring, learning how to "shut it down" with some protein or high fibered foods can help us get over that hurdle. In addition, if that urge to eat is too strong, learning the foods that you can eat in a larger quantity with fewer calories also helps. For protein, you may wish to try a small chicken breast, some deli-sliced turkey, a bowl of cereal with milk or a small serving of rice and beans. For those foods that you can eat a lot of, may I suggest Campbell's Select soups (Italian wedding soup or chicken noodle or pasta), salad with all the great "fillers" such as radishes, celery, carrots, cucumbers, mushrooms, green onions, green peppers? Paul Neuman's low calorie dressings add a lot of flavor with very few calories .. just shake it up with the salad in a large container with a lid to coat each leaf.
Barb is exactly right on mixing up the exercise. Log it into your exercise tracker to track your progress and be sure you're changing the many styles of exercise. Hope you'll follow here in the community as well as we try to offer various exercise each week that "mix it up".
Here is a link to an article on plateaus .. it explains how to break through a plateau with either food and/or exercise variances. http://www.medhelp.org/user_journals/show/40803
Very best wishes and please consider your regular participation in the community. We'd love to have you .. and hope you'll share your journey with us.
