Good to hear.
Weirdly I've felt the same since last Tuesday. All symptoms of a cold then Friday and Saturday were horrid. Literally all energy sapped, very chesty cough, blocked nose for 23 hours of the day. Weirdly felt much better on Sunday but then on Monday and yesterday it was as if those symptoms were starting to come back - managed to have a good clear-out of my insides (sorry no pics @MUFC) this morning which is good.
I carried on working on Thursday and Friday and regret it. Not sure how I did to be honest.
