Mr Squid - I find that being accountable to someone is a great motivator so if you do somethinglike WW and attend meetings then you weigh in in front of people and it gets written down! That way you know that someone is keeping an eye on you. I am doing WW by myself but I report in on a weekly basis to 3 of my friends so I am accountable to them for my weigh ins and if I stuff up they put me back on track.
