Date-shifting masking number of alcoholic beverages per week in discharge summary about mimic-code

[SichengH]

```select * from physionet-data.mimiciii_notes.noteevents
where HADM_ID = 120167
and text like '%11-26%';

The query returns no results. Likely this problem is already solved.

@SichengH take a look at the discharge summary for hadm_id = 120167 and you'll see that this is still an issue.

@vincentmajor thanks for raising this. We're continuing to work on reducing the number of false positives in the text.
