double spacing in memoir class

[Chad]

Hello all, I am writing my senior design project for college. My
document compiles cleanly... except when I ask to double space. I'm
not completely against single spaced documents, it's just a technical
document seems to be easier to read when double spaced. I (basically)
have the following:

\documentclass[...]{memoir}

\usepackage{setspace,ams...,etc.}

\doublespacing
.
.
. and so on

I have used the \doublespacing command numerous times before (in
report and book classes) without error, but can't seem to replicate in
memoir. Is there something I'm not aware of? Could somebody please
lend some assistance. Thanks.

~~Chad~~
