I encourage you to give colon hydrotherapy a try. colonics can work wonders in situations like yours.
But before going in I always recommend that you visit the therapist and examine the facilities. You want to make sure the studio is spotless and that you are comfortable with the person who will be administering the colonic.
Ask how long you will be on the table and if she will be with you the entire time. If the answer is about 30 minutes, and she'll help get you started but then leave you on your own, then I suggest that you seek out someone else. This is often the common signature of an ill trained therapist using a "Libbe" gravity flow system. You can achieve the same results at home by taking several enemas.
Here are a couple of links where you can find more information about colonics:
