Molly 2.0/Plür comedown sickness
I copped some of the new Xüm/Plür heart tabs containing the research chemical 5-MAPB.
I weigh 100lbs, took 4x25mg tabs about 8 hours ago, horrific comeup, couch locked the entire roll but still had a good time despite all, including occasional and sometimes severe muscle spasms. I've never done entacogens before, including Molly/MDMA/Ecstasy. My friend took 5 a few hours before me and redosed 100mg, had no comeup and no comedown aside from confusion and severe tiredness before sleeping (definitely due to an Adderall induced all nighter from yesterday). He also has a stimulant tolerance from frequent script stimulant binges.
My question is how do I deal with the horrible nausea/sickness directly after the roll starts to come down? I've thrown up 3 times in the last half hour. I haven't found any useful threads anywhere on Reddit and everyone only seems to suffer from the long term psychological comedown which I'm not currently experiencing.
I've already read the guides on all the subreddits, as well as the MDMA guide on DanceSafe. I haven't mixed it with any other drugs and I'm not on any sort of medication. I have Xanax, would that help? I'm not necessarily trying to sleep but if I must, then so be it.
