I remember several years ago I went through a period of a few weeks where I was eating fish 3 times a week, taking fish oil pills daily, eating fish eggs (salmon roe, ikura) at my local sushi restaurant, and eating several cloves of garlic a day with occasional additional onion intake. One day while shaving I had a little cut near my ear. It did not hurt, but it started bleeding a little. I rolled up some tissue paper and pressed on it. A minute later I removed it and noticed the bleeding continued. This time I pressed on it for 5 minutes. It was not enough. To cut the story short, it took me 20 minutes of pressing before the small bleed stopped. At that point I realized how powerful this combination was in thinning the blood. Since then I have reduced the amount I ingest and now my clotting has improved and is back to normal. I just wanted to relay this anecdote to let you know that too much of a good thing is not so good.
