I dont feel full

So I ma 2 years post op and have starting gaining but Iscut it off at the pass and am in control again. my problem is even when I eat 1/2 a chicken breast and vegis , I don't feel full. I feel like I can eat all day. Is this head hunger, I have been very stressed out and my anxiety has been at an all time high (no excuse, im owning this) so maybe that is what is making me think im still hungry. early out after surgery I couldn't eat chicken and then after year one I would get full on meat quickly. what am I doing wrong? I am logging everything I eat, staying away from carbs, drinking water, the scale is moving, down but I keep wondering "what if my pouch is too big now" what are your thoughts? thanks, I just wanna feel in control again.

A chicken breast should be very filling.  Are you drinking with your meal?

I recently had a couple of days where I could not get enough food in.  I was starving.  I realized I hadn't taken my vitamins either day.  I connected the two things together.  It seems logical to me, although I'm no doctor.  If I'm not getting all my nutrients in, via my vitamins, it seems perfectly understandable that my body would signal to me that I need nutrition.  As it can't signal to me that I need vitamins, it tells me I need food.  I came home from work at the end of day two and took my vitamins.  I've felt perfectly fine since then.  No crazy hunger.  Try taking an extra multi to see if it takes the edge off.
