Ok, so I have made the switch to soy milk, light soy milk even. I like it in my morning coffee, and occasionally at night. It doesn't taste that much different & is lower in sugar & carbs than cow's milk.
Now.
I bought some on a short ($7) trip to the grocery store the other night...and left it on my windowsill overnight. I stuck it in the fridge as soon as I realized.
Now for the big question--would you drink it, if you were me? I am poor & really can't afford to throw it away. Then again, a trip to the ER b/c I am deathly ill from left-out soy milk would be more expensive than replacing it.
Such decisions. *le sigh*
) but I got it from food that still smelled and tasted yummy (nasty, deceitful food! 
) Soy milk, on the other hand, neither smells or tastes yummy when its gone off. If it smells okay, I'd go ahead and drink it. Believe me, when soy milk has gone rotten, you know it as soon as you open the carton. You wouldn't even be able to get it near your mouth let alone swallow it, that's how bad it is!
