Why cant I sleep with a fever of 103.3?

So this all started out with bronchitis which obviously was accompanied by a moderate to bad cough and a little fever of 101.4. It's now risen to 103.3 which I already have consulted a doctor about. He says its all viral and you're going to have to let it run its course. Now I'm totally fine with that but what is annoying me is the fact that I'm only getting about 3 hours of sleep a night; the rest of the time my body just sits in between deep sleep and being awake. I've already taken tylenol pm which worked the first night but lost its charm the next dosage. Following that I took some Nyquil which also didn't work and was a terrible experience because I felt so confused and out of my body. I should be resting more but no matter how much I try to sleep(day or night) I always wake up every hour or so. Does anyone have any advice on why this is happening and if its a normal occurrence when it comes to a fever and viral infection? Thank you :)
