My father, about 85 years old, is addicted to laxatives. His potassium is low. we have been dealing wth this for the past 1-2 years. He has seen a psychiatrist and is on zolft. He live with my mom who has dementai and cannot remember anything. Dr. said no driving so he has her drive him around to the store and buys prune juice and laxatives. We confiscate them but he keeps buying them. we took away the car so then he would walk (he has a cane) in the middle of the night to go buy the laxatives. we gave them back the keys because we were afraid of them walking in the rain and dark. HE knows he is abusing them, he'll say, "I wish I never started to drink prune juice." but he cannot control himself.
