This is what I do, spurts of alternating heavy technical reading and heavy work, but it absolutely wipes me out (at the minute, I'd say 7-10 days a month I feel zombie-like), and i know it really pisses off my SO. It works; i absorb large amounts of information very rapidly, and i can apply that information usefully, but I feel similar to how the original questioner described their situation - the sheer amount of information often feels like a flood that's impossible to filter, especially when I'm weary.
