Lol, I know exactly what you're feeling! There is absolutely nothing like your fist time. ;-)
How often are you supposed to use it?
I only had to use it once to clear up the crud that I had, but I didn't use it for a sinus infection. I'd say that by now, since it's been over an hour since you snorted you'll be feeling how its working for you. If I felt like I still had an infection in the morning when I got up, I'd snort again.
I think I might wait and see how the snuff worked before I took the Super Tonic, but thats just me. If you feel like you need it then I'd take that too. ;)
Please let us know how it worked for you, I'm betting it helped alot!
