I am currently recovering from severe anorexia, my BMI is 17.5 up from around 13, nine months ago.  I have been eating regular meals following the advice of a dietician and have had consistent weight gain.  For the past four months however I have been constantly hungry, no matter how much or what I eat I cannot feel satiated.  I am hungry all the time.  I can eat and eat until I feel physically sick but still I feel hungry.  I have no history of bulima or binging but am terrified of this happening.  I have to take sleeping pills at night because I can’t bear the hunger pains.  Will they ever go?  What happens if they don’t, surely I will become overweight? Please help.
