I was on Zoloft 50-100 mg on and off for the last 20 years…mostly on. I did a long extended taper to come off of them and everything seemed to be fine. I’m at about month 3 completely free and I’m getting hit with the worst brain fog I have ever encountered. There are times where I get anxious because I’m afraid that it’s Alzheimer’s or Dementia and not just a fog. I thought things would get better, rather than worse. I am eating foods that increase my serotonin levels, trying to minimize stress, and getting good rest. Will this brain fog eventually lift? I need some good news. BTW – I just entered menopause about 1 1/2 years ago, so maybe that is causing it to be worse than for someone not at that stage of life.
