Is it possible for a physician to write a prescription for Sam-e tablets, or to prescribe an ongoing course of Sam-e injections? I used to take Sam-e years ago, with no side effects whatsoever. I now take a prescription drug which has serious potential side effects, two of which I am definitely experiencing. Yes, one of them is insomnia. My health insurance pays for the prescription drug, a factor. Another factor is, I now take care of my mother. She is a lovely human being who has done much good. She deserves truly good care, and most of my time. I must budget expenses closely.
