Vaping

I only got them from specific flavors, which I had the same issue with hookah back in the day. Some flavors made me nauseous and gave me headaches. For me it was anything mint, couldn’t even mix it with stuff.

For me it was also certain flavours, or if I vape too much in a short period of time I get massive headaches

it did when i when i vaped all the time. i felt so much better after quitting nicotine for multiple reasons

I got them depending on the juice. The one I don’t get headaches from uses all food grade vg/pg and flavoring(obviously the nicotine isn’t food grade lol)
