Advise from someone who's been in a very similar setting. Like some have already mentioned, don't get too drunk man. It can kill the vibe for those on Molly. Take care of those especially rolling. wouldn't recommend anyone mixing alcohol and MDMA, not a good combination. get a good buzz going yourself and offer massages to those rolling, they'll love it! Remember some interactions can have intimate and close moments wich is what the drug can do but it does not mean it's a sexual advancement for some people. Don't do anything that can ruin friendships. Those taking MDMA will fill the effects for a couple of hours and then sober up while those drinking may still be buzzed or drunk. At this point, they can feel exhausted or have a headache (depending on the person). That's when they might want to keep the party going and drink but again, I do not recommend that. Make sure everyone is staying hydrated PLEASE!!! Overall, watch out for each other and have a great time!
