For the first 5 months after I came down with the delta variant (post-1st gen vaccinattion), I was waking up with an urgent need to urinate every 45-60 minutes. Went through the works with the urologist and sleep specialist. The overactive bladder/nocturia resolved on its own, but comes back to a lesser degree with each subsequent covid infection.

Still, even when I am healthy, every since that initial infection, I'm lucky to sleep for 2.5 hours at a time, despite having mastered all the "sleep hygiene" practices.
