Jan, I have been on Tapazole for some 5 week – 4 days now. I had no memory loss prior to beginning the drug. Well, about 3 weeks into the drug I felt like I had ADD – roamed around the house like a lost person constantly. During that period of time I also was experiencing headaches and a terrible taste in my mouth – all of these side effects have gone now! Yea! As a matter of fact the Tapazole is finally doing its job and I feel so much better. Was just a rocky adjustment to the medication I’m sure now. How long have you been on Tapazole? Did you experience memory loss prior to taking this drug?
