You're really not missing much at all. Most over-hyped substance in recent EADD history.
I was sick of it two years ago, but not because I'm trying to be cool or anything; just because it ain't all that.
Do you mind me asking whether you have actual ADD, or self diagnosed (E)ADD, as seems to be all the rage around here? :D
Sorry to be intrusive, but I just can't see why anybody would choose 4-FA for ADD (or ADD-like) symptoms, apart from possibly in the very short term. Trust me, I tried.
I'm actually diagnosed with adult ADD and was offered Ritalin. A doctor confirmed the diagnosis just last week.
The reason? Adderrall and dexies I would just crush and snort, thus ending in a wankathon...no work done.
With 4-FA and low dose MDMA, I get increased productivity, my ability to concetrate on tasks is vastly improved and my writing skills go on the up, even with repeated long-term daily use.
For me 4-FA was always a productivity tool rather than a recreational substance, unless I was mixing it with methylone.
On it's own even after 250mgs bombs it never really hit all the right spots, I find the best substance to focus and do stuff(intellectual work).
I mean in uni I would choose MDMA at low doses over speed for essay writing, you're much more in control of what you write, with straight amp, I just go off the tangent, off topic, with huge paragraphs, plus I reckon both 4-FA and MDMA help creative writing, not only producing work reports.
It's a long chat we could have on the topic man.
My first ever assignment in uni was a book review on Adam Smith, did it on a pink heart, first a quarter, then another at the end of the essay I'd gone through the whole pill. Massive aid in concetration.
