I get sick to my stomach every time I read this. There's no excuse! I read the original through Dr. Wright's writing a couple decades ago, and treated myself to 75,000 iu vitamin A when I developed menorrhagia after a lifetime of extremely light periods. Totally worked. After many months, I developed headaches and figured out I had all the vitamin A I could handle. Went a couple of years without it, and now can tolerate 10,000 iu just fine. But I bless him for making such information available to us. Thanks, Wombat, for bringing this up when the need arises :)
