[runnerup]

Modafinil felt far more mild than amphetamine, methylphenidate, or cocaine for me. However, it uniquely (and dramatically) impaired my inhibition for libido compared to the others.

It was a very narrow side effect but also particularly destructive. It was very hard to tell it was the modafinil because it was so mild otherwise, just seemed to “front-load” all my energy and focus for the day into the first six hours of my work day, which worked quite well, and then left me feeling rather normal for the rest of the day (difficulty committing to tasks after it wore off but that is typical after a 6 hour of solid focused work).

I just had extra motivation and capability to flirt with coworkers and strangers and visiting sundry places. I was well-received, but it wasn’t the life choices I would have wanted to make and the workplace romance was self-destructive.

Amphetamine might make me masturbate more but only modafinil caused an impulse to flirt, court, and follow through.
