Many Catholics simply take the body of Christ (wafer) and skip the blood of Christ (wine). Personally I do not think drinking the wine is necessary if you have accepted the body of Christ.
In fact our Catholic church always provides the body of Christ but not always the blood of Christ. So it seems as though only one is necessary to provide a complete mass.
Also the extraordinary ministers who bring Christ to the home bound and sick are only given wafers, no wine, so it seems to me that the body is enough.
