Dear All, Thank you for your patience. Several things including a spell without use of my computer have held me up. They don't boot up when ya delete the Sys.Ini file just before shutdown. I could go on, but you don't want to know. In recovering my PC, I lost all of my saved e-mail, so I have to resort to the list to reach all of you that wrote. However, that is not the only reason I am as late delivering on my offer. I am sorry to disappoint anyone, but I wish to "First do no harm." I thought of that as I waded through various charts and other trappings trying to set up a presentation. It occurred to me that such an approach could make my knowledge of this product look scientific. Reduced Nicotineamide Adenine Dinucleotide (NADH) is a "food supplement" with enough potency that it should (IMHO) be sold as a drug in this country. I HAVE NO IDEA HOW SAFE THIS STUFF IS WHEN TAKEN WITH OTHER ANTI PD SYMPTOM DRUGS. In fact, the only thing I KNOW is that I am convinced the ENADA brand substance I bought from Menuco Corp. IS EFFECTIVE AS A SYMPTOMATIC ANTI PD MEDICINE. My use of this substance has been frustrating, slightly frightening, and difficult. From my point of view, most of my problems stem from the conservatism of my physicians. As far as I know the sole authority on the safety and effectiveness of this drug is Dr Georg Birkmayer (of Vienna.), the patent holder. Because of its nature (marketed as a "food supplement") and the fact that controlled studies had not been published in a suitable journal, my doctors were not willing to contact Dr. Birkmayer. I soon found myself taking a substance that I felt as potent as a drug, without any back up from a physician. I can say that it works, but I also want to caution anyone taking this substance. Unless you have a physician willing to be innovative, and with the patience to fax or call internationally to ask questions, you are on your own. This product is not listed in any formulary or the PDR. Regards, WHH 55/38/37
