I have an oral presentation in two weeks and I'm already so anxious I want to cry. So far I've contemplated drinking before the presentation, simply not showing up and dropping out of university. I can't do this.

I was prescribed beta blockers for oral presentations about a year ago. I take the maximum dose (the highest dose my doctor said I'm allowed to take) but it still doesn't help as much as I'd like it to. Last time I had to present I felt like the beta blockers completely failed me. This presentation is bigger than the last one and it's in English (English isn't my first language), which makes it even worse. Much worse.

What do I do? Are there any other kinds of medication I could try? Something to take just before a presentation that would calm me down but still keep my head clear enough to go through with the presentation?

Thanks.
