Forums > Food & Drink > Coffee Creamer?

I like to make coffee in my room, but I've been getting a lot of conflicting messages about how long the unrefrigerated milk you can buy lasts. I don't have a refrigerator and I don't want to worry about the milk going bad. Someone told me it's good for two days after opening. True? Also, can I get anything equivalent to powdered coffee creamer?

Thanks!
