hunger pains over eating

Does anyone with ADHD or Autism or both have sever hunger pains or are unable to stop the constant urge/impulse from wanting to eat and eat and eat all the time all day and through the night. I have both sever hunger pains and a constant urge/impulse to eat. It's not my medication. Medication i was given for my diabetes was also supposed to suppress my appetite instead it seems to of done the opposite. The doctor admitted they hadn't work for me. My doctor told me not to take these tablets for a week to see if they would help with the server tummy pains. I'm at my wits ends. I'm totally lost again has to know who to stop it and to stop putting more and more weight on. I am already classed as morbidly obese.

I just wanted to know if anybody else is like this with my doctor telling me it could be connected to my ADHD and Autism. I'm just waiting for a correct diagnosis of the consultant when i get an appointment to see them in the near future.
