Extreme hunger though "normal" weight?

I have a weight in the normal range. If it is my set point weight, I honestly have no idea since I have battled with anorexia since I was around 8 (now 23).
Though my concern is that I experience extreme hunger. So "extreme" that it actually gets me sick. Like last night, I had chocolate and ice cream for dinner because that is what I felt like, but then I was awake for hours during the night with extreme tummy ache and acid reflux ( I will also mention that I have not had chocolate or diary for over 2 years, so it may also be related to that). I will be honest and say I am scared of gaining "too much". No matter what that is haha. But is it normal to have extreme hunger even though I am not underweight? Can I really trust it and can I really always eat as much as I want? Even when i am weight restored? (I know a lot of this is ED talk but it is so rooted in my mind because I grew up being told these things. It helps me to hear other peoples output so I am not alone with this silly voice).

Thank you for your time and help!

P.S I probably eat around 5000 cals a day with the extreme hunger. Is that normal when you have a "normal" weight already?

YES IT IS NORMAL. It doesnt really matter if you are - or not - underweight. A starved body is a starved body and it needs to repair the damages, no matter for how long it was starved/undernourished. If you are experiencing extrem hunger then its the proof that you were eating too little and your body needs loads of yummy ice cream and chocolates to heal itself. And no, you wont have extrem hunger for the rest of your life, it will pass ONLY if you listen to it every single time! xox

Thank you for your reply! I will munch away
