I had the Astra Zenica one, (Oxford), Thursday morning. Felt good all day then when I sat down in the evening started getting a bit of a headache, (never get headaches), and started feeling a bit chilly. An hour later I was sweating but felt absolutely freezing and my head felt like it was trapped in a vice. Into a very hot shower for half an hour, 2 paracetemols and an Ibuprofen and into bed. Slept like a log for 11 hours, normally get by on about 5 or 6), and woke up feeling back to normal.
Been told when you get the second one it doesn't affect you as much, if at all.
