I currently have it, and I'm triple jabbed. The symptoms are very minor: started with sneezing on Saturday. Went for a run on Sunday, felt tired after and ran slower than usual, then more sneezing, runny nose. Monday was the worse day, but even then it was pretty manageable, very faint headache, a bit of fatigue, runny nose and more sneezing. I think I coughed a couple of times. Yesterday, less bad than Monday, but similar symptoms. Today I feel pretty good. Normal energy levels, clear head, clear nose, no sneezing. So, hurray for vaccine! No loss of anything, quite the opposite, I felt famished, especially yesterday!?
I did two lateral flow tests and 1 PCR - waiting on PCR, both lateral flow were positive.
Thanks to the new 7 day isolation period I can be back in the world sooner too. Not that I'm going anywhere
edit: I also know LOTS of people testing positive right now, in and around London.
