Days 1-3 days very mild symptoms - tickle in my throat and slightly chesty, productive cough. +ve LFT at the end of the first day.
Days 4-6 Felt worse. The kind of cold symptoms I’d have worked from home in more normal times - did some work through the headache but slept most of the afternoons. Very sleepy, blinding headache, diarrhea for a few hours, horribly weak wobbly legs one day, lost sense of smell, dizziness.
Day 7 - Felt pretty human again (still headaches but not weak) thought I was on the mend
Day 8-9 - High fever for two days. Symptoms all returned. Sense of smell started coming back.
Day 10 - 14 Temperature back to normal. Still headache and dizziness and fatigue but feeling better and symptoms reduced over the days. Had one afternoon completely symptom free! Left the house for very short walks (3-500m).
Day 15 Feeling as though I am definitely over the worse. Headaches and dizziness only with more exertion. I think it will still take another week or two to get back to work fully - part of my job is very physical.
I have been pretty cautious as I suffered badly from CFS when I was younger.
I would say that if you have a case that is more towards moderate than mild to watch out for symptoms continuing / getting a bit worse in the second week (I read somewhere here that docs say days 7-10 can be the worse). And that 10 days is the isolation period, it does not mean that you will be ready to go back to work then. To me it felt more like flu but without the delirium!
