Oh yes the dread constipation which I know too well. A few things I have tried I will suggest. Prune juice or baby prune food,healthy fats lubricate and ground flaxseed which was suggested you can put in oatmeal which has fats but also fiber,adequate water,for me I think the magnesium I take helps to an extent,enough fiber from whole foods but not too much. I am not sure if you can do any activity but that helps I think keep things move. Coffee aids sometimes or other warm beverages.
