Best combo for a first rave? Struggling to balance low energy and anxiety

I’m looking for something to keep me wired for <8 hours. I’m bored of coke, MDMA makes me too anxious, and I am way too sane to risk a bad shroom/acid trip in a new environment but I know my depressive ass would be sitting down by hour two without a booster. I have thc and ket on hand and I could probably source any other common drug. Thoughts?

Bonus question: Is there a common etiquette for finding dealers on site? My city is known for shit purity but if someone had I’d hate to miss the opportunity to at least buy for future use (Pretend I didn’t ask if this violates rule 2)
