How long would you survive?

When you wake up, it is quiet. You aren't sure where you are and you don't remember how you got here, but you are pretty sure that your bed isn't this uncomfortable.

Your eyes aren't closed but you cannot see as you seem to be blindfolded. When you reach to remove the blindfold, your hand stops suddenly before you can touch your face. After a few moments of disbelief, you realize that you are restrained with some kind of bonds around your wrists.

You didn't notice it at first, but now that you have had time to clear some of the fog from your mind, you realize that wherever you are stinks. The smell is so bad that you gag. Thankfully, you are able to (barely) avoid throwing up.
