Help me out ya'll?

I'm one of those people who can't purge... I'll sit there with a toothbrush down my throat for ten minutes or jam my fingers as far down as they can go, and get nothing. After another attempt, I think I've figured out what I've been doing wrong.

Is it possible that I can't seem to purge because I've been drinking diet soda right beforehand? I know that water is my friend... but even that has to be carbonated. *I'm a tad obsessive* So could having so much carbonated shit inside me be what's keeping me from getting anywhere?

Ack, somebody help me?
