Don’t bother with consumption in general (3,2)

I believe the answer is:

let be

'don't bother' is the definition.
(to let something be is to not bother it)

'consumption in general' is the wordplay.
'consumption' becomes 'tb' (consumption is a name for TB or tuberculosis).
'in' means one lot of letters goes inside another.
'general' becomes 'lee' (Robert E. Lee - US revolutionary commander).
'tb' put inside 'lee' is 'LET BE'.

'with' acts as a link.

I've seen this clue in The Times.
