Your constipation problem that began during your first year of college is not unique. The transition from the relatively protected lifestyle we experienced growing up and through high school comes to a sudden end when entering college away from home. I can tell you that I have met many people (almost all women), who trace the roots of long standing constipation to their college years and the circumstances you describe.
I presume that by now you have an enema bag and use it as necessary, but living in a college dorm makes this a difficult option for most students.
I'm happy that you have had the opportunity to experience colon hydrotherapy. colonics and can help restore natural muscle tone and peristalsis to your colon and promote a healthier and happier lifestyle.
