Sidney, what kind of anti-depressant are you taking? I am also suffering from candida and SEVERE brain fog and fatigue. I was on Prozac for about 6 years with only minimal improvements. About 3 weeks ago I started taking Lexapro and the fog is about 90% gone now. Like you I was almost about to give up. Lexapro and a new Dr. was my savior. There is hope, please hang in there!
