what do I do.... can't poop even after suppositories and senna laxative.  Had suppositorie at 3:15 this afternoon and it's now 6:40 pm.  This has been happening to me since I started a new drug for my kidney failure, it's called vasotec 5 mg.  It's been going on for about 3 weeks.   Please help me cause I really can't much more pain, may have to go to the emergency room.
