A strange reaction to fish oil

I have had a strange reaction to starting fish oil capsules.

My skin feels very very oily, my taste buds have completely changed and foods (especialls sweets and tea) taste really different, and I have noticed yesterday when gardening my body odour was different (not bad just different smelling to normal). I am only taking a low dose of the fish oil, I capsule every second day. Has anyone else noticed symptoms like this?
