It sounds as though you are suffering from chronic constipation. Have you talked to your doctor about this? Prolonged, excessive use of laxatives can make your constipation worse as your gut can become reliant on the laxative. Excessive use of laxatives can also cause diarrhoea and fluid imbalance which can damage your kidneys.
