First of all, do you take any other depression drugs, or mood disorder drugs such as
SNRIs and SSRI ?
If mixed with these, zoloft can cause
serotonin syndrome. This includes fever, sweating, muscle stiffness, trouble thinking clearly, a change in mental functioning, sleepiness, or change in your breathing, heart
beat and blood pressure disorder.
If this is the case, you should stop taking zoloft
and speak to your Doctor.
