We address the problem of including Coulomb distortion effects in
inclusive quasielastic 
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approximation, which is no longer applicable in its original form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.
