I can only relate my experience. It was positive. I told the nutritionist the things I COULD not eat and things I WOULD NORMALLY not eat. We agreed that the things I could not eat would remain off the diet (peanut butter) but that eventually, I'd have to try things I would normally not eat (like butter or cheese) when I was stronger/healthier.

My nutritionist didn't have me count calories, since it's so triggering for me. I did count dietetic units ... like I was to have X number of starches, Y number of proteins and Z number of fruits/vegetables. At first, I was always under the count. Then as my metabolism improved, I found myself getting hungrier. This scared me very much, but it was then that I could try to eat some of the higher calorie foods that I wouldn't normally eat, because I knew my body was burning off the calories.

Over the first few weeks, it was very very x 30 hard, but then suddenly it was much easier.

Once it got easier, I got stupid. and relapsed. But now I'm back to following the meal plan and I have to go through the hard part again, but this time I KNOW it will get easier and I know not to be dumb.

Good luck tomorrow. I'll be thinking of you and hoping that you have a good experience and learn a lot.
