How much is too much of laxative (constipation)?

Generally I am: Not in favor of chronic laxative use. A hi fiber diet along with 80-100 oz of caffeine free/alcohol free fluid per day usually corrects the problem. You are approaching the age for colon screening and if the above doesn't work for you after trying for 2 weeks minimum, you may be a candidate for a colonoscopy even at age 46 or at least an evaluation. Tlk with a colon and rectal surgeon or GI doctor.
