Yes. It is. Don’t worry about it because even if you wanted you won’t be able to eat like before. It happened to me also. Not only that, I actually got depressed because all I wanted was to eat, eat, eat! That was the moment I discovered how much I used food out of emotions. I got bored, sad, angry but then... it all went away. Give it time. Your brain needs to learn, and it will. Congratulations!
