Anti-depressants, such as
Zoloft do not normally present significant
withdrawal symptoms, but, as with any psychotropic medication it's best to seek to advice of your physician before discontinuing it.
If you choose to do so without the advice of a doctor, it is best to slowly reuce your dosage each week until such time you are completely free from the drug.
You may still experience strange sensations, such as dizziness, sweats, confusion, etc.
