At least you came to know that no type of medicine can be taken in excess. It was good that your mother caught you, otherwise i dont know for how many dyas more would you have taken the pills.
But you are right, the benefits of cod liver oil are many. It helps fight and prevent heart disease, cancer, depression, diabetes, ulcers, hyperactivity and many other diseases. It also Increases your energy level and ability to concentrate and provides greater resistance to common illnesses such as flu and cold.
So have the medicine but only one tablet a day.

I vividly remember the name of the tablets that are avaiable in our local market. It sells by the brand name of seven seas cod liver oil. The bottle consists of hundred tablets which can last for 3 months and I have been giving one tablet to each of my two children before they rush off to school. No wonder they are healthy and outgoing. I will have to touch wood for that.

I used to take these tabltes when I wasa young boy going to school for my cold. I used to catch cold easily and the doctor had recommended the tabs for me. But then I also consumed homeopathy medicine for the same and as I grew up the attacks of cold and cough reduced. But as a precautionary measure I stay away from drinking cold water and also avoid eating ice creams
