Ah, right: "My peak concentration is usually right before break and after break it's generally gone."
One thing I do is, before I take a break, I dump my current notes, as well as things I'd like to do, into a Google Doc. When I return from my break, I take the time to read the notes, which loads pertinent facts back into working memory and gets me back into it.
Another practice that helps is that I let a fine-grained todo list guide me during work. I make sure to explicitly mark what I am currently working on. If I get distracted, it is straightforward to remind myself what I was doing, and once I am done with it, I know exactly what I should be doing next.
