You may become dependant on the laxatives and get chronic constipation. To combat this, try lots of fruit and prune juice which has natural laxative properties. However, if taking chemical laxatives long term have not affected you badly yet, I wouldn’t worry about it. Simply, switch to a high fibre diet.
You must take fiber in diet and plenty of water also. Eat leafy green vegetables, beans, nuts, and dark chocolate that contain magnesium, have warm water with lemon that will show you the good results.
