For the past few years I've taken both Adderall and Vyvanse, with the past 2 years being Vyvanse. I thought I would be taking these drugs for the rest of my life if I wanted to be successful, because when I didn't take them, I could not focus on work tasks at all. However, the "cost" of these drugs for me was that I couldn't turn off. I was driven from the time I woke up to the time I went to bed. My social life definitely suffered.

So, as I started a new job this year in January, I decided to make a clean break. I quit Vyvanse cold turkey and started a new job. I've been doing exceptionally. I never thought this could happen. Thinking back on the issue just yesterday I was telling a colleague that I thought this was likely because I must have been bored with the tasks at my previous job, and I've found all the new tasks to be interesting enough to bring out what I consider great performance from myself, though not the insane amount of performance I was doing on Vyvanse.

Anecdotal at best, but I independently came to the same conclusions as this article, for whatever it's worth.
