Fredd, thanks so much for answering!!! I'm sending you a virtual holiday hug. Concerning the carnitine - I just purchased the l-carnitine fumarate, but reading your above message, I do have anxiety and I would say I tend to over emphasize fears. Does this mean I'm one of those 10% you mentioned who needs the plain carnitine rather than the carnitine fumarate? Or will I eventually need the carnitine fumarate?
