the purpose behind the vit e enemas is not to promote bowel movement, it is to deliver the healing vit e directly to the inflamed tissue of the bowels. that is a big part of your problem, the inner tissue of your bowels are inflamed and swollen. i think either vit e or fresh aloe vera or both would do you a lot of good delivered via an enema, or orally, or both. hemp seed oil might help, i really don't know.
i personally don't think you should be fasting. you should be eating small, sensible, healthy, meals throughout the day.
