I've been scared for the longest time to try this, but mega intrigued about the whole narrative around it. I think people on social media love to dramatise how "bad" this is... and while I agree that it's a bit repulsive, it's not for the reasons that people describe it. Most of it I think it's the preconceived idea of what the marketing around it creates, though I have to agree, the metalic note in this will throw you into a confusion that will offend you and others trying it for the first time. Having said that, 3 days later I keep going back to see if my nose has adapted to this new experience, and most of the times it smells clean and crisp.
