Uncontrollable urge symptoms and conditions

I was surprised and enlightened to read the side effects of Zoloft (or its generic) from other users. I took Prozak for years. It didn't seem to be having the same effect so I asked my dr. about changing it. My brother takes Zoloft and it does wonders for him, so I asked to try Zoloft. I am taking a generic form now. Since starting taking Zoloft, I have experienced an almost uncontrollable urge to eat. Not just when I am hungry, but eat until I am miserable. It was comforting at the time, but discouraging to see my weight increase. It was very difficult for me, since I have always been able to control my weight and to lose weight when I tried. My gastroenterologist told me that I should lose some weight, that the extra weight around the middle would cause pressure and add to my acid reflux. I also experience a feeling of "fuzzy" headiness, with difficulty concentrating or remembering things. Some nights, I find it very difficult to sleep.

weight gain started almost immediately i gained 20 kgs during both pregnancies on zoloft. Although my anxiety/panic and outbursts of uncontrollable anger, and irrational thought patterns all stabilized remarkably on zoloft I have NO interest in sex, and uncontrollable urge to drink alcohol and I cannot stop until i pass out. Also, void of emotion ...haven't cried in years despite traumatic events that have included the deaths of grandparents, a divorce in the family and a miscarriage. Each time I try to go off this stuff I end up experiencing amplified symptoms of my original problems as well as severe depression and paranoia so I get scared and go back on it.
