Stage fright?: People who are anxious in front of others (such as giving a speech or other performance-type activity) can forget words or lose their place in a planned talk. Supplements like theanine may help you calm down some, but working with a psychologist might help you more. Also, low-dose propanolol (your doctor can prescribe) before your talk may help some of your anxiety symptoms.
