A quick update for myself.
It has been 2 weeks, and all I am left with is the cough. It's much better than several days ago (when I almost coughed my soul out). Now it's like 2 or 3 coughs per hour, and it doesn't hurt anymore.
Another symptom is sleepiness. My friend said it's a new symptom after he got covid. But for me, it has been a year, since I sleep at 2 am and wake up at 11 am. I really need to sleep early, right?
