I would suggest drinking plenty of water because I know from my own experience that dehydration can lead to migraine. I always without fail take headache pills to parks because I usually get one. Could it be motion sickness related? If so I can’t recommend Cinnarazine highly enough (you can get it over the counter called Stugeron 15). If none of the above are sounding any good then I’d avoid Zodiac, Saw and Colossus, - the latter 2 have crazy head banging moments which I’m sure have killed off some of my brain cells in the past
