While I can't relate to all the TOM stuff, I will say that this was a big problem for me in the first month of my process, but grows less so each day.
At the beginning I didn't only miss feeling full I missed feeling STUFFED! Which is crazy because I would always feel so miserable for hours after stuffing myself full of junk.
For me it was teaching my belly to understand a whole new category that didn't exist previously. Before my belly knew three categories
Hungry>>>>>Full>>>>>>Stuffed
Now I've added another category although it doesn't always work right
Hungry>>>>Satisfied>>>>Full>>>>>Stuffed
Now this requires a deal with my stomach. I promise that him (mine's a guy lol) that if I can stop when satisied, I will not starve him to long before feeding again, and if I get hungry I'll eat a snack.
While there is conflicting information about the metabolic benefits of eating 5-6 small meals, eating more frequently and smaller has really helped me in the area of conquering the "fullness" issue.
One other small note is that sometimes if I'm really feeling super unsatisfied I find it might be because I've overcut either fat/protein/carbs. Like I'll realize that the day before I ate almost no carbs and adding in a few gets me back to equilibrium.
