Query: Re SamE

I have not read the book but would like to report to the general public that I am a perfectly healthy 46 year old man who within one week of taking 800 mg/day of Sam-E was stricken with a nearly fatal pulmonary embolism from deep venous thrombosis. I am from a very distinguished medical family (including the world's singular most influential cardiologist) who is certain that the increase in homocysteine levels produced by SamE are intensely thrombogenic. During my 3 week hospital stay, I was tested in a search for any possible medical cause for this episode, from the obvious to the "zebras in Montana" and the etiology remains idiopathic. BE SURE NEVER TO TAKE THIS "SUPPLEMENT" without simultaneously increasing your intake of Folic Acid, or it can be a killer.
