@Dorual glad you managed some sleep, sorry you are still feeling so rough. It's good that your o2 sats are high.
Please keep drinking plenty and eat at least something-I used to manage soup on my worst days, if nothing else.
Steaming may help your chest/tubes. Are you coughing anything up?
Please remember you can call 111 to speak to a doctor if you are worried/need reassurance, or feel things are getting worse. Quite a few of us have had to be checked out at some point and received supportive treatment in the form of antibiotics or inhalers and even being told you do not have pneumonia if you are struggling to breathe can be immensely reassuring.
