I was just looking at a Zoloft page regarding side effects, because I just recently started taking 50 mg as well. It says to call your doctor at once if you have worsening symptoms like trouble sleeping and restlessness. Here's a link to the page:
Look under "Zoloft side effects" for more details. You may want to check with your doc about this, and remember not to stop taking it without talking to your doc first because this medication requires weaning. Stopping abruptly can have nasty effects.
