day for 11 years. I went off it, gradually to start another drug, which ended up making my illness worse. now I would like to return to Zoloft. I am extremely nauseous, am living on ginger and other herbs which are not doing me any good. Should I cut my pill in half, and go on a 25 mg for a week . and then increase it . I am female and 75 years old and my physical health is good. the extreme nausea has helped me lose 20 lbs in the last 4 months without really trying.
