I believe it was 40g a day which is two tablespoons of fish oil, after six months you should of achieved your goal, and also checking free fatty acid profile (if your taking the test) it should be good then you can go down to maintenance level, when at maintenance levels there may be some days when you don't need to take fish oil supplement if your eating high omega 3 foods such as mackerel, sardines, other fish and maybe some wild meats depending on quality of where you live in the world, just watch out for your omega 3 to 6 ratio, while taking the fish oil this wouldn't be a problem though unless your are someone who consumes high omega 6.
hope this helps in some way
