Does anyone know if I can take L-lysine while nursing?

I have had a pretty bad diet the last 2 years due to being severly hypoglycemic and am worried about cardiovascular disease. I know that Lynus Pauling did research in taking large doses of L-lysine and vitamin C to quickly reverse arterial plaque build up and I think it's important that I do this. I do not however, want any harm to come to my nursing son. Does anyone have any experience with this?
