Hello, ramakentesh:
If I can, I fast--takes four or five days; water only. Otherwise, eat plenty of borage seed oil capsules--by the mouthful for at least 2g GLA and in addition to this drink fresh wheatgrass juice on an empty stomach--about 4-6oz once daily for 3 days in a row.
Don't want to discuss in-depth enemas but they are good and sometimes (when I had AS...) I take small 'retention water' with SSZ, which when uncoated dissolves rapidly in water.
In 15 years I never had to break down and take any NSAID except the 5ASA in SSZ.
Hope You find relief quickly,
HEALTH,
John
