Hiccups wind me up, they are funny fot the first 5 seconds but then they start to peck head
Coughing probably annoys me the most though, that wakes me up at night when I'm not well
Sneezing is ok as long as it's not one of them powerful ones that you have to brace yourself for, it makes me feel like I've sneezed my ovaries out every time

All 3 wind me up, but coughing pips them all because there's nowt more annoying than beingwoken up ]:<
