I am new to this forum, but not the others. When you say you have "liver cleansed my way down to 90 pounds"? This does not sound normal. I think the cankers may have to do with the loss of weight/dyhydration...
IMHO, it sounds like you are not taking care of yourself with proper food/supplements and your immune system may be reacting to this. LFs and general cleansing needs to be done to improve the health. Please slow down the LFs...eat healthy...try to gain weight properly.
BTW; I have taken Oxypowder with no adverse reactions.
