Some people can't shut up and think what they are saying is the most important thing in the room... yes often those with a huge ego, though also those without, thosr who desire otherwise.
For me, well, most of us love a bit of that - it just doesn't make me chatty or give me banter. Definitely prefer amph for that.
One thing I will warn is that it will likely become the end of any MDMA scene you're involved in. Most people will be chasing another henry on chucky, leaving the club earlier and earlier. The banter and vibe will gradually change, with people chasing a tiny bump that won't even do anything. Up for days with shite patter, people get bored and tend to drop out. Apart from the odd one who still has a fixation.
