I don't recognize the term "Lexamile" at all, so have no idea what it is or what it contains. If you can see a GP for a prescription, the best bet would be any of the heart / Blood pressure drugs called Beta-Blockers. While they may not help you to feel less psychologically nervous, they calm the body -- slow the rapid heart beat, cut the sweating and trembling, and so on. And it shouldn't affect your performance skills.
Some might suggest benzo tranquillizers ( the Valium family ) but these have snags --- they are sedative, and you don't want to nod off during the presentation ! And they can interfere with memory.
In the medium term, Cognitive-Behaviour Therapy ( CBT ) can help you to unlearn all that nervousness and grow confident as well as competent in such public presentations. Also in the longer term, some drugs also used as antidepressants can reduce these forms of social anxiety, but not within days.
