I'm using pro-gest to limit my monthly auras and it's a life-saver. What upsets me is my lack of concentration (it's definitely getting worse as I get older) and my reluctance to take responsibility for things. I take 800mg of Tegretol per day and have used this drug since I was 9 yrs old. I'm already showing signs of perimenopause at 42! I had my thyroid removed 5 years ago. Anything to help my foggy thinking would be greatly appreciated. Thank you, Kate
