I don't believe this is a solution for all. I'm not even suggesting you have an unhealthy lifestyle. It might sound funny, but increasing the amount of protein helped me stabilize my focus for long period of time. It was amazing realizing how each macro-nutrient regulate the mode of focus differently. For example, carbs+coffee gives me multiple small bursts of focus throughout the day. While, protein+coffe gives me a single, long and steady focus for 5-6hrs a day and that's it. Sometime, I have hard time stopping and getting out that 5-6hrs of intense focus. Having said that, I don't believe that you can have 24/7 steady focus, it is not reasonable (it is not even needed)

What foods do you consider protein for your purposes

Mostly lean protein from meat. I've been trying collagen peptides too, and it helps.
