Is the No Red Face Formula legit? I'm thinking about buying it, but am still skeptical...I have a huge family wedding i'm in and really want to be able to drink there! I just got laid off so $40 is alot for me to  be spending. Can someone that knows about it please give me an honest answer? (Someone that doesn't work for the NRFF) Will I really be able to drink without turning red? Thank YOU!
