Drug test tomorrow after taking codeine?

I have looked all over the internet, but thought some of you with experience could help me. I have a pre-employement drug test tomorrow and I took codeine yesterday. I am drinking a ton of water, using a product called Nature's Secret® Super Cleanse™ from GNC. I am also taking a Creatine supplement, multivitamin, and a B complex vitamin. I plan to take a product called Omni Cleansing Soft-gel right before the test.

Is this enough to possibly get a negative result. I know it's not a guarantee, but if anyone has had any experience with this I would really appreciate it.
