quitting screws with your blood sugar levels for at least the first month
quitting screws with your digestion and can make you constipated the first month
quitting gives you an oxygen high for the first month.
also, outside light seems brighter the first month.
you have to keep your blood sugar balanced and unless you exercise, you have to cut back 200 calories per day to adjust for not smoking.
i suggest mixing cranberry juice without added sugars 1 part juice to 3 parts water to balance your blood sugars and not pack on the weight.
