Yep, epic fail.
en route to chipper with DP and a whinging baby in the back to get chips to eat on the beach in the carpark. Romantic night in eh?
PR DP's migraines have been attributed to all sorts of weirdness over the years: too much sleep, not enough sleep, too much caffeine, not enough caffeine, apples wtf? and laterally mature cheese (I have tested this one, it is not true)
Anyway, he usually gets them when coming off nightshifts so not enough sleep and too much caffeine are the main culprits.
