1. Where in the mouth should I place my posterior tongue? Is it right in front of the uvula.

2. Also, I've been mewing as much as I can for the last 2 days (I just started), and I've noticed that my tongue hurts. Is that normal?

3. When I push upward, I try to push up hard enough that I can feel my cheek muscles and jaw muscles. Unfortunately, I can't hold it long enough. Am I doing it right?

4. I've heard that when you start mewing properly for the first time, you should be having difficulty breathing. Well, I'm not having a whole lot of difficulty breathing. My breathing isn't completely restricted

5. When I push the posterior third of my tongue onto my soft pallet, the front third of my tongue loosens up and it drops down. Like by focusing on my posterior third, I lose the ability to focus on my anterior third. So my entire tongue kinda looks like a long U. Does this just get better with practice?
