Hey, I've been having some breathing issues for the past six months and it's bothering me a lot. Im a 26-year-old guy with a lean build, but my belly sort of sticks out and I'm wondering if its related. Every night about 20 minutes after I fall asleep, I wake up suddenly feeling breathless and like my throat is narrowing. Drinking a glass of water seems to help, and then I can sleep through the rest of the night. In the morning, there's this discomfort in my upper chest, along with a weird taste in my mouth and it feels dry, which wakes me up. Sometimes I notice I clench my teeth in my sleep too. I've noticed whenever I eat, whether it's lunch or dinner, the discomfort in my stomach and chest gets worse and my breathing problems intensify. If I lie down for a while, it seems to help. And if I have a drink, the next day's breathing and eating feel even more difficult. The tightness in my chest and stomach is really noticeable when Im sitting down. Also, I walk 4 kilometers daily. Could these things be connected, and what should I do about it?
