Hi! I Had A Weird Thing Happen Last Night And

Nothing to worry about.
Detailed Answer:
Hello and Thank you for choosing "Ask a Doctor" service for your query,
Have seen your details and I appreciate your concerns.
As per the reversal of diet after bringing a new companion is concerned it has been probed in various researches that owning a dog can lift your mood and help a person feel less stressed. Dogs can help people feel better by providing companionship. Dog owners including those who have posttraumatic stress disorder (PTSD) can experience these benefits.
PTSD is a pyscho somatic disorder and various emotional aspects are involved in it and as said above researches have proved that pets like Dogs and Rabbit elevates mood of the owner and raises level of feel good hormones called Endorphins.
Now as far as fever is concerned I don't know the status of Covid19 at your place but as you have mentioned that fever is not there any more my suggestion would be that just leave it unless an episode of fever returns back...Because even slightly increased anxiety levels could revert back the level of Endorphins in your brain...
Spend more and more time with your Dog/Any thing which makes your symptoms better...
It's good that you are feeling hungry(A sign of recovery).
Breathing exercises(PRANYAMA) and YOGA NIDRA would also be very helpful in your case(very easy to do just YouTube them).
For fever as it's no more there just forget about it and feel happy that your appetite is back....Calm down and relax.
Follow ups are welcome,
Thank you!
