Dave- parasite cleansing is really hard on the adrenals. I would recommend some coffee or plain water enemas. Make darn sure you are having at least one and complete bm per day.
I don't know if you have ever considered NB but if you are cleansing and are mineral deficient than this will be a rough ride. I know because I did this for a couple years. Once the mineral levels are more balanced it is much easier for the body to cleanse and resist new infections.
