Oh dear. In a strange way, most addictions can be kicked with the same sort of approaches - whether women (or men !), substances, behaviours etc. or Playstation II. There are usually some underlying triggers - sort those patterns out and the challenge gets a lot easier.
I hope your brother takes steps to control things - everyone has to face down their demons eventually, it's getting mentally prepared and willing to do it that (hate to say it but ... ) gets easier with practice !! Bail-outs are not always the best solution but if this is a recent thing it may be easier for him to sort himself out.
Always sad when these things have to be addressed but good for him for coming clean and telling his family - what he really needs is help to get things under control. Heck, we all have our vices (I sure do !) but have fought very hard to control some of them for my own sake and the sake of everyone else
