Very similar to you. Had double Pfizer. Felt like crap on a Sunday, felt worse on Monday so skipped work and took a lateral flow test which came back negative.

Very similar to you. Had double Pfizer. Felt like crap on a Sunday, felt worse on Monday so skipped work and took a lateral flow test which came back negative. Same symptoms but for maybe 5 days. Lost my sense of taste on day 3 which was also the day I tested positive (I didn't take a test on day 2). I stopped testing positive a few days later, but taste was lost for maybe a week. I had a cough for maybe 10 days, which has just subsided. I can't tell if I have brain fog, as my cough was really preventing me from sleeping well. One interesting observation: I was pretty ravenous the entire time. I had a fever and was sweating like a pregnant nun in church, but I never lost my appetite. If anything, it turbocharged.
