perhaps your problem is not completely diet related. You may have some kind of underlying medical condition that you need to get to the bottom of. this is something that you def need to talk to a doc about. when you finally DO go from a laxative is your stool hard? because if it is soft/liquid, you may have some type of blockage. Sometimes if we have constipation for a long time the stool hardens, we take laxatives, and the bowel behind the blockage turns into liquid and passes BY the blockage and comes out, but the main blockage remains causing your problem to never resolve.
