So, do you think I should gradually phase out all the crap?
Like say I would drink 2 cans of coke a day, drop that to a couple a week, and things like that?

I'm trying to replace crap with good, by drinking blackcurrant and water today rather than fizzy coke.

I need to plan a healthy diet, so I can buy the stuff at the weekend and prepare for each week as it comes. When I fail to plan, I just eat crap all week.

I have tried before completely cutting out fizzy drinks, only to bounce back on to them a few days later.
