Which drugs? I've been writing an application for 4-5 years. It's my "learn a new language" project and it's pretty complex and I recently rewrote it and exclusively worked on it under an influence of one or another of things, but nothing like Adderall or Ritalin. I just finished the final version of this project in Go and it is far and away the most readable, performant version I've written. It's also the first version to properly protect against all types of races.
