Andreas is away over the weekend (from forum #2). So until he returns and can answer you more completely, I would recommend downloading his books. First I would suggest the Amazing Liver Clease. I believe it will answer many of your questions regarding your symptoms.
The Key to Health and Rejuvenation may answer some of you questions as well. I highly recommend both.
I put the address at the bottom. Just click on the Books button. They are under $7US when downloaded.
