** Thanks for contacting with your health concern 1. Dulcolax [bisacodyl] is a mild laxative that provided relief from constipation and because you are taking them for 4 years running thus although there are no known documented ADR [adverse drug reaction]of the drug but still using it for a long time, surely your intestine must have developed an addiction to laxative and in best interest you should taper it gradually and most importantly because you are in recovery process under no circumstances you should stop/start/or taper the drug dose without first consulting with your attending physician. 2. Some common lifestyle and dietary modifications which one can incorporate into his daily activities to overcome laxative abuse is/are: *Regular bowel habits with attempted bowel movements 15-20 minutes after breakfast when gastrocolic reflex is strongest. PS. regular walking + Yogasanas to improve the tone of abdominal wall muscles * High fiber diet: green vegetables, fruits, raw bananas. * Adequate fluid intake: a glass of hot water in the morning, with 1-2 tablespoon ghee, and if needed prefer a bulk laxative like Isapghul, Kayam Churan, or Triphala Churan PS. Do not give the same laxative for very long time, change the drug frequently. 3. Glycerine syringe or Dulcolax suppository or simple soap water enema, if drugs fail.
