I've had problems with the scent - and I think it's because my sinuses are chronic - and sensitive. The scent would leave me nauseous. I've devised a system that works for me, but it requires a swimming nose piece (holds the nostrils together) and/or putting the mix into a sippy cup with a straw.
I'll be glad when my toxicity levels drop enough that I can get past this point.
