Percocet used for pain relief is a narcotic medication and prescriptions can prevent people from getting high on Percocet without medical reason.In fact, the Percocet high feeling can get you into lots of problems.
I think the formula of the perfume itself decides how fast it will spoil. My perfumes from Britney Spears Curious and Salvatore Ferragamo went bad within a year and a half. The Britney Spears one developed some precipitation and started smelling like alcohol, while the Salvatore Ferragamo just smelled plain weird.
The odor was so bad, I could have smelled up an entire room. Use about a teaspoon of yogourt, and with your fingers, apply it directly into your vagina as far up as you can go. You should then be good for the day. Do this daily until the odor goes away. Once yogourt is applied, the smell goes away instantly.
