I'm not giving up anything, I would give up booze, but I very rarely drink and lent actually contains some of the odd days in the year when I might have a drink haha. I very rarely eat crisps so would be no point giving them up, chocolate I have most days but that's what I use my syns on.... when I'm already so controlled on slimming world I don't really see the point in giving things up as I've given a lot of them up for the majority of the year anyway... if anything I should have more during lent haha.
I might try something new during lent though, not decided what yet, but maybe eating more of something, or using syns at least once a week on healthier options?
