Be sure when you snort the first time to exhale away from the line of snuff then inhale that line with a DEEP inhale. Don't pussyfoot around with it just snort it all in at one time. I'm not gonna lie to ya, you'll feel like the top of your head is gonna come off! But after about 15-30 minutes you'll notice a difference for sure. You'll feel it unclogging and working up in your sinuses, it feels strange. Do the other nostril as soon as you can get your eyes to stop watering lol. You'll know what's coming with the second line and it might be harder to do but I'm telling you it will knock that sinus problem on its butt!
