David Garrick research query

[Kathy Kit Chung]

I am trying to locate the source of the following statement for
annotation purposes:
 
    "the sentimental heroics of a David Garrick--who you remember
     deliberately got drunk in the play in order to repel the young
     girl who loves him"
 
 
1) Did Garrick perform in a play where his character go drunk to
     repel some young woman's love?
2) If so, which play?  (I've looked through Garrick biographies
     without much success, did I miss something?)
3) Was this an incident from Garrick's own life?
 
Does anyone have a clue or suggestion?  Any help would be
greatly appreciated.  Thanks a lot!
