I also discovered that dehydration was a migraine trigger for me. I tend not to get big headaches now but get quite intense visual aura / disturbance.

Interestingly I also discovered that electrolyte supplements were also migraine triggers for me.

Leading me to think that electrolyte imbalance was the actually trigger. Caused by too little water increasing the concentration or added salts increasing it.

I tend not to feel thirst very strongly and think I do often confuse it with hunger.

I pay loose attention to urine colour as a gauge and make sure I drink plenty, kinda robotically when playing sports / walking in heat etc.
