If you don't already have an enema bag I would encourage you to purchase one as soon as possible, and don't hesitate to use it whenever you feel the need. Some people will tell you that you should avoid enemas because there is a possibility that you may become dependent on them for relief, but if you are already habitually constipated, enemas are a far more preferable alternative.
A properly administered cleansing enema is a natural, safe, and effective method to relieve constipation.
