Zoloft (sertraline) makes me feel like i can't sit still, muscles tensed, poor sleep. should i find another ssri or will it eventually go away? taking for anxiety

Zoloft (sertraline) substitues: You can try prozac, Marplan or effexor (venlafaxine).

Try other medication: If you've been on the zoloft (sertraline) for more than about a week, talk to your doctor about switching to another ssri. If you've been on the drug for a short time, the stimulating effect may go away. Otherwise, another medication may benefit you without the side effect burden.
