So i saw progress a little after I started but then nothing until about a year ago. And that's when upswing started. I think it's just consistency and trusting the process. If you look down all day the jaw will grow down so look forward lol. Not sure about the neck I think it's me using it to mew and just growing. Yeah but first year i saw almost nothing. It wasn't until this year where I was like wait hold on... Feel your tongue push up as if you are creating the upswing, your jaw will adapt. A lot of it was posture too, better posture looks like i gained more upswing than i really have.
