you've gotta rememeber that if your being weighed in the evening then you will obviously be heavier, and it takes a good 4-5 hours for food to be digested, so think of all the food thats still in your body when you get weighed, could EASILY equal half a lb if not more! honestly hun, its so normal...i mean you saw i gained 4lb last week! but already lost 2 of them, so im guessing it was mainly water
