You're doing too much mate that's why.
My pals are on halfs, full ones + at those doses and you don't get the same come up, they just send folk messy.
There's only so much serotonin that can be released at once and it doesn't take anywhere near 240mg to do the job.
Pills back in the day were 80mg ish, those there are like triple dropping.
Sure there's personal tolerance but it doesn't vary that much, there's still only a finite amount of serotonin at any one time for anybody.
The reason why these modern DN pills are so strong is because they're getting the precursor cheap as fuck from China and it can be shipped legally because it's not watched.
Molly oil is illegal, what they're getting is Molly oil that's been dried to powder (in effect) which isn't illegal.
All they have to do is add acid to it to make it oil again and then it's like 1-2 steps away from crystal.
There's pretty much no chemistry knowledge involved anymore.
Plus the big commercial guys want to brag that they've got the strongest shit around.
