I have been on Zoloft since June of this yr. I was depressed, had anxiety attacks that felt like heart attacks, racing thoughts, felt unnecessary in this world, cryed alot and felt like I was going to be fired at my job all of the time. I feel better on Zoloft. My moods are more even. I work nights now and am alone from 5p to 11p. I have had headaches alot lately. My dreams are pretty vivid and I wonder if I lived it or if I dreamed it alot now as well. I asked my doctor about this product causing weight gain and she denied that it did. In fact she blamed the steroid shot I had for allergies this winter for the hunger I have felt. Maybe so, but I was eating before that and now that I have found this site I am afraid that it is the Zoloft afterall. I am on 75 mg's. I have felt a bit dizzy at times, blamed allergies, now I am not so certain. Also, after I eat I have been feeling nausea too. Zoloft? I do not know. Is there anything a person can take or do that will remove the anxiety, racing thoughts, depression etc without feeling other horrible effects to feel better? Now I am afraid to go off of the drug. I certainly do not want to return to the way I felt, or the mean mood swings or the pains that felt like a heart attack. I also sweat alot at nights while sleeping. Thought it was menopause? Don't know. What do we do? Other than the dreams, sweats, overeating, stomach upsets, racing to the rest room etc. I feel okay. HA.
