I've always had trouble breathing properly, especially in the morning after years of smoking. I was skeptical about the effectiveness of a spray, thinking it would just be another cheap remedy. But after a few days of using Nerivol, I noticed a marked improvement. My cough is less persistent, and I feel truly light when I wake up. What particularly appealed to me was the fact that the product is 100% natural and causes no side effects, unlike some medications I had tried before. Nerivol has given me a new chance to breathe freely, and I highly recommend it to anyone who, like me, wants to continue enjoying their life without sacrificing their pleasure of smoking.
