No. But I have experienced very noticeable increased difficulty in focusing over the last years. and I am treating it in another way. Right now what I'm doing is: taking less coffee, sleeping more and cutting down on news, social media and "doomscrolling". Now that I'm already on a different routine I see that my smartphone was the biggest cause of the problems I was having. I thought all that information (especially on Reddit) was adding something to my life, but it took me a long time to realize it was taking away much more than it was adding. I should cut more on Hacker News, I already have the "noprocrast" mode on. Replacing those old habits with stuff like mindless gaming (games that you enjoy but don't require a lot of your brains) really helped me. Also, B12 vitamins. Have you tried any of these?
