Constipation is a fairly common problem in those who use narcotics on a daily basis. Often it is seen in cancer patients
being treated with high dosages of narcotics. Omega 3 is a good option which may help. In addition, you may need to try laxatives, although these may cause bloating, gas and cramps. You can also try what is known as a bulk cathartic, such as psyllium (Metamucil), which will increase mass but soften stools.
