In my case it's the combination of too much caffeine, dehydration, and intense exercise where my HR maxes out. 2/3 risk factors will typically not be enough to trigger one for me. HIIT workouts and soccer have done it in the past.
The aura (with scintillating scotoma) starts coming on usually an hour or so after the exercise is done, and I know I've got about 15-20 minutes before the actual migraine hits. Got prescribed Sumatriptan and it maybe reduced the intensity by about 25%. I'll have to try the water chugging, maybe with rehydration salts to speed up absorption.
