Barb - I would be interested in joining a group to purchase ENADA brand NADH. I've been wondering what the markup is. I'm also having some good results with Ginko Biloba along with the ENADA but it isn't terribly expensive. Also, thanks for your info from Dr. Iacono's lecture. I definitely am a Type "A" PWP but can't think of any major life traumas, unless divorce and raising kids as a single mother counts. I've had emotional ups and downs but doesn't everybody? I appreciate the info, it is certainly food for thought. I can also relate to the seratonin deficiency but didn't know about bananas. Carol Phelps [log in to unmask]
