I got covid back in May 21, lost sense of taste for around 6 months, than had horrible congestion and insomnia and fatigue since. The insomnia hasn't gone away yet. I got covid again a few weeks ago, and was given some antivirals (Molnupiravir), I recovered super quick on those, and for the days I was taking it I had the best sleep I've had in years. But after the course ended the insomnia returned.
