No. While they may give you new energy and a greatly improved outlook on life, anti-depressants do not change you. Your personality is the product of your genetic background from your parents and many years of influence at home, school, and in your community. Your personality will not be changed by taking a medication for a few months. But if you feel less spontaneous or blander, let your doctor know so that you can consider a different medication.
Are anti-depressant medications addictive?
No. Anti-depressant medications are not addictive. In most cases, they can be gradually decreased and stopped without problems.
