two-day edm event use?

hello redditors

I have a two-day event (ASOT Rotterdam) and I planned on taking mdma on day 2.

on day 1, I’m still trying to figure out what to take and I have 2 choices, either 2cb or lsd. also it will be my first time ever taking lsd or 2cb.

from what i’ve read online, it isn’t suggestible that i take lsd first time in a overwhelming environment. for 2cb, what i’ve understood is that it’s less likely to have any bad trips.

any suggestions on what to take on day 1 without it interfering with the experience i’m going to have on day 2 with mdma?

I’m also open to mixing mdma with 2cb or lsd on day 2
