Hi everybody,
I'm new here so I apologize in advance if this isn't the appropriate place to post this topic!
I'm 18 years old and I got the gastric sleeve on March 27, 2017. I've been having no problem drinking Water and getting my clear fluids in, but whenever I drink anything thicker it feels extremely heavy in my stomach. Additionally, I was scheduled to begin puree yesterday and I had scrambled eggs mixed with cottage cheese for lunch, and chicken puree for dinner. I feel extremely sick and am feeling deterred from eating any other pureed food as I still feel sick from yesterdays. Everything I try to eat seems to make me nauseous.
Since I am 18 years old, I live with my mother. I know she means well and is worried about me, but she is constantly asking me if I have had enough Protein. I don't know what to do because I feel like it's physically impossible for me to consume that much now no matter how hard I try. The lack of protein over the past weeks has been getting to me as well, I feel dizzy and tired all the time.
Does anyone have any tips on light foods that pack a lot of protein in them?

It's all about food portions now, controlling how much we eat and what. A calorie is a calorie you choice if you want a healthy 100 calorie snack or an unhealthy snack. I just totally forgot where I was going with this. Ah well!
