Ok...once UNEXPECTED challenge is having to actually be accountable for what you are putting in your body. It used to be, eat it, feel guilty, then forget it. Now if I eat something bad...IT HURTS ME. Like not just a full feeling and throwing up, but feeling lethargic, gassy, acidy, and having non stop hiccups for like an hour. So, it makes you mind what you eat and pay for not doing right. There are some things that , even if I am having a super craving for them, I just stay away from (the worst is BREAD!!!).
