That sounds like a fairly typical cold, maybe edging to "bad" in my experience. I'm double vaxxed plus a booster about 1 month ago, and currently have Omicron. I have roughly the same experience as you, although less on the coughing, which is odd because I usually get a lot more coughing with colds.
> That sounds like a fairly typical cold No, it doesn't. I've never felt "wiped out" from a typical cold.
Omicron now is no different. Ended up taking 3 days off work and am now back to normal capacity.
