I agree with you that zoloft does make a person gain weight because i have taken zoloft. Not only did Zoloft cause me to gain weight, but it also did nothing for me but make me a zombie. As for getting off of the medicine, it should be done ( as with any medication) carefully and gradually. I think mabey you should try another doctor. As for me, i am now taking lexapro and it seems to help some with depression, i have taken it now for 2 years and have not experienced any weight gain from the medicine.
