...the dangers of akrasia circumvention techniques which simply shunt willpower from one place to another and overstraining damaging your willpower reserves.

Easy answer: don't use willpower. Ever.

I quit it cold turkey in late 2007, and can count on one hand the number of times I've been tempted to use it since.

(Edit to add: I quit it in order to force myself to learn to understand the things that blocked me, and to learn more effective ways to accomplish things than by pushing through resistance. It worked.)
