A technique that works really well for me is to focus hard on the fact that my job is to be merely a conduit for information, and any anxiety I might feel is just another factor that might impact my ability to convey that information. My feelings then become secondary because my whole focus is on the message. Sometimes I still get an adrenaline rush at the start, but this dissipates as I focus on the content. Other times I am completely relaxed throughout.
