Judges do not automatically put this type of clause in in Texas, however, many do when requested if there is a basis for the request.  There is no guarantee that you particular judge will impose it, but you do have a decent chance of getting the clause, especially if your child has been mimicking the behavior of if you ex- has any documented history of alcoholism related issues (like a DWI or public intox arrest).  Some judges will just order it as a matter of course-- depending on how conservative your county is.
