'advice from specialist you find here?' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'early rest the treatment' is the wordplay.
'treatment' indicates anagramming the letters (letters treated or processed differently).
'early'+'rest'+'the'='earlyrestthe'
'earlyrestthe' anagrammed gives 'HARLEYSTREET'.
