Hi Crambo, I have struggled with an eating disorder since I was a teen--I am 36 now. At first anorexia and then bulimia too. I had some stressors in my life a few weeks ago that caused me to restrict my diet way too much. But, other than the last 2-3 weeks, I have been doing really well and eating in moderation without purging.
I was on a diet for 22 months and lost all my excess weight the right way. I lost over 40 lbs by just eating sensibly. No fast food. Limited amounts of meat and bread. Lotsa veggies and fruits. Butter substitute. Diet soda.
22 months is a long time to be on a diet, but I had to take it slow and not fall back into restricting and purging. For me, it was all about eating in moderation--that is a very difficult thing for me to do. For this to be even remotely possible, I had to be in therapy and work on my personal issues that affected my body image. I had to deal with my emotions instead of eating them away.
I urge you to come up with some type of plan about how you are going to eat and not restrict, purge or binge. Take it slow an don't try to change everything overnight.
