i would try a few different types of oils like pure flax oil, pure borage oil, and pure wheatgerm oil, pure hemp seed oil, etc. experiment a bit and see if all of them make you feel the same. its possible you can find one that works for you. most people do well with hemp seed oil and its a very well balanced oil too.
perhaps ask on the dr. sutter or dr. biamonte forums, they might have some insight.
