Please help.I have to do a transit study test but will need to come off laxatives 2 days before and 5 days during the test.The problem is that I am so dependent on very high doses of irritant laxatives like senna and cascara, that when I stop taking them I become very ill and am in excruciating, debilitating pain. I am also unable to eat, move or function. I have problems with nausea and pass out a lot. When I tried to do this test in the past and explained the problem to my doc, his response was "just do it" ... well, I took his advice and landed up in the ER!!The second time I tried I tried to gradually taper off the amount of laxatives, but this too caused so much problems and I became very ill. Its taken me nearly 3 years to decrease the amount by 1/3 and am still struggling.Am I the only one in this situation? Surely there must be some way of doing this test and being able to survive?Ihope someone can help, I am really desperate and dont know what to do.
