Metabolism slowed, gaining weight

I am trying to recover from binging and purging and decided to go on the atkins diet. I have gained like 5 pounds in 2 days! How long does it take for your metabolism to go back to normal. I know I screwed it up by starving and now it's conserving everything I eat and storing it as fat, but geez..... how long already?

You might not want to hear this, but in thirty years of suffering with an eating disorder (and now 15 years in recovery) I learned that diets don't work. They pretty much don't work for anyone, but they especially don't work for those of us with eating disorders. They tend to set off our obsessions. My suggestion would be to stay away from radical diets and learn to eat healthy foods with reasonable portions and give your body and your mind time to recover.
