Are you talking from personal experience or is Modafinil really known to be a powerful willpower booster?
(If it's the first case you might start from it's mechanism of action and figure out YOUR cause for "willpower barriers" and maybe find a better solution for them...)

I haven't found any medical studies, but it matches the experiences of myself, others I've talked with, and online anecdotal sources.
I initially put it down to it being used when people are sleep-deprived (as I find willpower is easier when sleep-deprived) but it's even more effective when rested.
