Got omicron last week. Got really exhausted on Wednesday at work. Went home and tested, nada.
Stayed home from work anyways on Thursday because I was coughing a lot and felt like crap. Tested again on Thursday night: positive.
Felt like crap (though not debilitating or anything) on Friday and Saturday. Started feeling better yesterday and aside from a little fatigue, feel 100% today.
Sudafed is a hell of a drug.
