mouthpiece continued..
I tried.. I tried to wear the mouthpiece and sleep. It didn't work. I felt sick because of the strange feeling from wearing it, so I took it off. Then I woke up tomorrow morning, and I almost lost it. Actually, I found it by my pillow. Because it was kind of early, I decided to go back to sleep again wearing it. It was a bad nap.. I don't know if I could actully sleep. It's really hard for me to sleep with it. I think I might fail to make the shape before I use. hmm.. don't know..
