I've been listening since the start and was sorry to hear you've been struggling Steve. I've been really into this podcast http://www.fat2fitradio.com/
and they have some really good advice on lifestyle changes. Also get onto zap120 guy Davo he was over 300 and he's down over 100 I think. Bend his ear and get some support. Forget about having to do it again. Just start today and tomorrow will take care of itself. All the best
