Ok a new thing has been happening to me. yesterday i noticed i was breathing really really hard and im like wtf i sit up theres this heavy wheezing noise and its strange because i have to leave my mouth half ooen alittle in order to get some air and im not an asthmatic... so when i went to bed last night it was like i was choking in my sleep and even when i talk i have to take breaths in between . can anyone tell me why this is happening or is it happened to them?
