I think it would be fine. To be honest, best performance zero anxiety - I'd take nothing, as long as (i don't know 8-12) my habits are in place.
Otherwise maybe something, but in general -- things that make me smarter, better, more focused... make me less sociable, less outgoing, less charismatic a bit.
Not all of them, but a lot. For instance... When I did take dex, and similarly if I did take choline -- I'd use it to PREP for an interview or do the work to realize what it is I want to inteview for. MOST interviews, I'd be ok on them (one for sure, and I expect the other in moderation however, it is a different feel to "normal" a bit). However, I'd be happier, actually smile, not be as agitated... off of it. Sometimes it calls for it though, like if otherwise, I'd be late, or barely slept... or realistically I would not prepare till last minute. Same with a lot of things, like presentations. I've done them nervous, and very well.
I've done them all stimmed out (most are crap except for 2 I can think of). I think for me, presentations, I might run into an issue, of being QUIET--or too quiet during it, on Alpha GPC or Citocholine. --- AGPC has phosphatidylserine. Note, this happens to a lot, not to everyone.
Also, I've done enough school presentations high/wired, hungover, many, with zero sleep (most?). -- Alone, they were almost always great. 5-10 idiot group members? yeah I got lost... Went in the wrong order, was paired with crybabies, etc.
Work is more natural, can BS easier. Schools filled with either millenial snowflakes or old elitists on the other side (hence, better on own).
If it's a solo presentation, you could practice a bit... on phosphatidylserine and off. ---Well, that could be done if it's a group presentation too -- it may just be tougher to arrange.
