How much Meclizine can I take over the course of my lifetime without getting dementia?

I know there’s limited research on this and you can’t give me a definitive answer, relax 😂

But maybe you can weigh in and help me feel better: do you think it’s a lot or a little?

I work in the maritime industry and sometimes get seasick when the weather is rough. At most I would say I take 25mg 2 to 3 times a month when I am at work, never when I’m on land. So maybe 15 25mg doses over a whole year. I’m in my late 20’s. Will my brain be scrambled by the time I’m 65?
