About Marcus
I’m Marcus — just someone who went down the modafinil rabbit hole during a rough stretch of work and started writing down what I learned. This is an honest account, not a textbook.
The short version: I spent most of my twenties in product and ops at startups, burned out properly at 28, and spent the following year trying to work out what actually helped — sleep, caffeine, schedules, and eventually modafinil during a crunch period I’d rather not repeat. Some of it worked. A lot of it didn’t.
I’m not here to cite forty studies. I’m here to tell you what it’s actually like to take this stuff, what I got wrong, and what I’d tell a friend.
If you want the deep clinical breakdowns with real citations, there are better sites for that and I’ll link out when it’s useful. This is more “here’s what I wish someone told me before I ordered my first batch.”
