Handling Nerves at Auditions

Hi all... I'm wondering if anyone can give me some options for handling nerves at auditions. I'm affected by them quite severely and I truly believe they let me down immensely during auditions. I've heard many theories including: - Knowing your material well, being well rehearsed - Breathing/meditation/imagining you're on a tropical island sort of thing - Seeing your audition as a performance and knowing the panel want you to do well So, with all these checked, and short of taking some mind-altering drugs, what else can I do?! Does anyone have any food remedies? It really is a sad thing because as soon as I walk into an audition room, my voice falters, my heart beats a thousand beats per second and my hands get all clammy. Also if there are any current WAAPA/NIDA people out there, could you please let me know how you think you fared in your audition that got you into drama school. Did you feel extremely confident after your final audition? What did they panel say to you? I will be auditioning next month.
