Did you ever get a satisfactory response to your message. I think it was Jan of 2004. If so, please let me know. I, too am suffering from extreme itching. Not familiar with Terazol 3 but tried Threelac for 10 days and itched so bad, I couldn't sleep. Like you, I'm wondering is this die-off, new candida or what. I've have stopped Threelac, 2 days ago and am working on my diet, but I know I need to do something else. Please respond to email@example.com. Thanks! All the best.
