First time advice

Bit of background of tripped on mushrooms loads of times in public lower doses and higher at home and camping. If tripped acid twice. And tried ketamine at a rave once. I have silver Mario 2cb pills which I believe are around the 16mg Mark? I'm going on a stag for a weekend so a few questions. Me and my friends are all pretty experienced going to raves and doing drugs but don't know how much 2cb to take? Can we take it two nights in a row? Was planning on low dose for bar crawl Friday night then maybe 1 pill for a club Saturday with 200mg mdma does this sounds a good plan? Just don't want to get freaked out by having too much and wasting the stag weekend!
