For the past 3-4 weeks I've been sleeping terribly. I fall asleep relatively easily but can't stay asleep more than 3 hours. I don't feel any more stressed than usual. But here's my main question. Upon waking up (which I do many times throughout the night), a change in position causes a sensation that's new to me. It's like it was physically taxing on my body to move from say fetal to sleeping on my back. My heart doesn't race or I'm not totally short of breath, but it feels weird...hard to explain. When I do take a nice deep breath I feel normal again..this odd sensation is very brief, but it's happening nightly. I feel like I'm breathing fine. I do notice that the number of inhalations/exhalations slows down dramatically when I'm relaxed and in a near state of sleep, but that's "good" and normal I thought?? I read as few as 5 breaths per minute is a nice target.
Other facts--38, male, otherwise healthy, and exercise regularly.
