I eat far too much sugar and I drink far too much Diet Coke, so I'm going to give up both for October.
I've tried having both in moderation, and sooner or later I fail. I've tried giving up both for good, and sooner or later I fail. I reckon I can get my head around the challenge (and finite time) of just quitting both for the month. And 31 days is long enough to feel a difference.
I'm not suggesting a month-long check-in thread, I name change too often for that. However, I would love to hear from anyone else considering something similar and I'd love to hear from anyone who has managed either, and what the benefits were to them.
