I've used it to get ahead in software for the past ~8 years. I recently gave it up, but it was hard to realize that it was time. It might be time for you, too.
The thing holding me back was fear. Fear I wasn't enough, that I couldn't be efficient. That I would get fired from my high position. Or even if I could make it work, that I still wouldn't get enough done on my startup (which has its own list of fears itself).
What finally pushed me to quit was realizing I wasn't as compassionate anymore; it was impacting my relationships. I had three separate people tell me in my coworking space that I look too busy and unapproachable so they never came to chat. I had a SO tell me that I'm emotionally unavailable too often. All within the time span of a month. I'm naturally an optimistic, compassionate person. This wasn't me, and being a robot (as mentioned in the article!) wasn't who I wanted to be, at any cost.
Indeed, three days after I quit I felt like a new person. I felt silly, fun, again. I had a week of "brain fog" where I wasn't productive. Afterward my efficiency went back up. Nowhere near the Adderall levels, but to a very acceptable level.
So in summary, you might not need it anymore if it's causing you grief. Sorry for the lame motivational things I'm about to say (Taken from the book, Daring Greatly):
You are enough.
You are worthy.
