Could someone please explain why when I have about 2 pints of milk a day and sugar as well (could be white tablesugar) my body bloats up.I know this because when I eliminate the milk and just eat potatoes as carbohydrate soure then after a couple of days I urinate a lot at night and then my abdomen seems to shrink down.I know this because it no longer protrudes.when I do bloat up I do kind of look very fat in the middle.Other thing is when I do cut out the milk and sugar then sleep is just impossible.Potatoes don't seem to have the same effect as sugar(sucrose,fruit juice etc)Thanks for any help
