Zoloft and loss of appetite?

You state you have no appetite and yet you say "But I am hungry"... I'm a little uncertain about this conflict. If you can get yourself so worked up about eating something snack-like and smooth like yogurt when you're worried about nutrition and then cause yourself to vomit, you either misstated something or you're very upset and/or anxious. Anxiety can cause you to lose your appetite or be hungry but barely able to eat. I just can't tell where you're coming from.

A common side effect of Zoloft is decreased appetite or weight loss. The frequency of weight gain isn't known and would be common if plenty of people were reporting it. After 2 weeks you can still be experiencing temporary side effects that will go away anytime now. It's a short enough time to wait out the side effects. I'm more concerned at the way you describe yourself getting worked up and vomiting. Zoloft isn't doing this to you, are you bulimic? Or very anxious? If you are either, you need to see your Dr. and possibly get a referral.
