  We address the problem of including Coulomb distortion effects in inclusive
quasielastic (e,e') reactions using an improved version of the effective
momentum approximation. Arguments are given that a simple modification of the
effective momentum approximation, which is no longer applicable in its original
form in the case of highly charged nuclei, leads to very good results. A
comparison of the improved effective momentum method with exact calculations is
given. A critical remark concerns recent experiments with inclusive
quasielastic positron scattering.
