I have a question about fish oil supplements?

to start out with. how many of you take fish oil supplements? i had a 4 way heart by-pass in 1996 and my dr. the other day put me on 1000 mg. of fish oil supplements 2 times a day. she said my cholesterol and blood pressure was just a little high but not too much. she said high blood pressure is,nt a very good thing for people with heart disease. what i,am asking is of today is there any more findings the benefits of taking fish oil? all i read was like 1 or 2 years ago. i been to several doctors and none of them ever mentioned to me about taking fish oil but this dr. said it would be good to bring down the cholesterol and blood pressure. i like to know what your thoughts are on taking fish oil supplements. thanks a lot ! i appreciate it very much.
