I am a mouth breather. Everytime I tried to breath trough my nose I felt like I'm out of breath. I barely can breathe clearly when it comes to my bedtime or before I sleep. I'm not someone who snore when sleep. Even when I sleep with an open mouth, I'm not snoring. But that's not just it as I have a smell sense problem. I cannot smell anything except when that thing has a strong smell. My sense of taste actually affect too but it is not as extreme as my smell problem.
