Whether people take anti-depressants or not, one of the most dangerous times of treatment is during the initial lifting of the depression. The person has gotten a blessed moment of relief and suddenly reawakens to the fact that life can be better. Then he has a setback for a moment, or a day, and that brings on a black hopelessness. This is when people attempt suicide.
