Can too much oil be harmful?

I have done seven Liver Flushes within 5 months, also used to take a tablespoonful of Udos's choice oil or flax seed oil daily. I have stopped taking the oils (except when flushing) since I noticed my bowel movements floating all the time. I was told that this is an indication of poor absorbtion of oil. I take digestives enzymes, but that does not seem to do the trick. I hate to take somethink that my body is rejecting, although the "good" oils come highly recommended. I am somwhat confused on this.
Has anyone on this forum had any experience with this?
