Back to the original topic, I just wanted to add that I was going to do my syns weekly but when I mentioned this to my counsellor she really advised me against it. She gave me three reasons why not:
1.It tends to perpetuate that "diet" mentality, of starve then binge (but in a less extreme format).
2. It also encourages you to be just that little bit too restrictive on the days when you're having less syns, which can lead to overeating
3. Some people eat all their syns in the first days, and then end up playing catch up ie they have to reduce their syns
All of this is about the games our minds play when we think we're on a diet. It doesn't apply to everyone but definitely does to me, which is why I try and stick to my daily syns rather than going weekly.
She also said another mind trick is to count down your syns rather than up. So start with 15 (or 105) and count down to zero, rather than starting with 0 and counting up. Its a little thing but she said people are more likely to feel they have to stop when they reach 0, whereas if they're going up the numbers its easier to just carry on. Would love to know if thats true!
