Although there was no theoretical limit on how much one could use the Force, physical brains would feel the burden of accumulated stress from continued use of the Force. Usually, this would not happen for a while, but a side effect of Rayleigh's use of multiple Wills meant he accumulated mental fatigue and stress multiple times faster than normal. A seasoned and well-trained Jedi Knight could probably maintain a single use of the Force for several hours before reaching a fatigue limit. Rayleigh's limit while using nine Wills, was less than an hour.
