I Don't understand why so many seem to have had such an issue with the 1-day treatment; perhaps they have a very different chemical makeup in their bodies than I, or perhaps they were trying to treat what wasn't a yeast infection with yeast infection medication, but I had NO discomfort WHATSOEVER using the 1-day treatment.
I was extremely skeptical before purchasing it, but I experienced instant relief in many ways, and had no burning, stinging, itching, or discomfort of any kind related to the product itself.
I used it during the day because I was otherwise ill and planned to spend the day in bed, anyway. I did get up and move around a bit which did lead to some leakage, so I of course would recommend that unless you are completely confining yourself to your bed, follow the directions and use this overnight.
Anyway, the next day my symptoms [which had included INTENSE itching, burning, and severely swollen labia minora] had improved some 85% and the day after that I felt 100% symptom free!
I would absolutely recommend this product to anyone with a confirmed yeast infection. It is much less of a hassle than the, 3-, 5- and 7-day products and it works wonders, in my opinion =)
I would have given more than 5 stars if I could have!!!
