I haven't looked at all of the enormous corpus of akrasia articles on the site, but I haven't seen a lot on "decision fatigue." I tend to over optimize and over thing a lot of decisions, treating the ability to make decisions as if it's an infinite resource. Turns out it's not.

Be careful with the model of decision fatigue. See Robert Kurzban's criticisms here: http://www.epjournal.net/blog/2011/08/willpower-is-not-a-resource/.

That blog post makes a fundamental flaw in it's analysis.

If indeed the correct explanation for poor performance were that a resource has been depleted, then X shouldn't matter.

Where X was any number of things that he shows does matter. But saying that you have limited resources to make decisions in no way claims that nothing else matters, so showing that other things matter doesn't really bear any evidence against a theory of decision fatigue.
