I don`t think pain is a good sign. I think it`s a sign that your body is in distress.
Uniquyty`s comments sound correct.
The coffee enemas and Epsom Salts drinks are useful for dealing with a painful situation right now. You need to address the underlying condition, or you will likely continue to experience these pains and get sicker over time. An Epsom Salts drink and/or coffee enema could be used any time you run into trouble (have pain) while you are busy cleansing your body.
If you have a lot of parasites, you need to go through the cleanses, starting gently and watching for problems.
It sounds like the garlic remedy should be reserved for further down the road, when you have already gotten rid of the worst of the parasite problem.
It`s best to do all the cleanses, starting with the parts furthest away from the liver (colon cleanse plus parasite cleanse) and work through the cleanses until you get to the liver flush. That way, the ducts will be less likely to be blocked with the debris you eliminate from your system.
