Had my jab about a week ago, and feeling increasingly rubbish as the 10 day incubation period date (22nd May) approaches. Neckache, constant headache, very very dodgy stomach and generally just really lacklustre. I've checked the side effects and we've pretty much got all of them as above so we must fall into the '1 in 10' category! Did anybody else have this and how long does it last? We'll be on the malarone next week so the thought of the two combined - just lovely! Thanks all.
