To 'Wring out the leeches' is to spend time solving a problem. Said problem will often 'suck the life' out of you- hence the use of leeches as the explanatory word for problem. Wringing out the leeches is also used to describe an impending argument over an issue with a mate. Phrase is said with much trepidation and detest for the action.
