Side effects

When I went home last month, my sister was asking me the possible side effects of diet pill to those who are taking them. Since I am new to our company (we sell diet pills), I could not really pinpoint particular side effects. So I tried to ask some of our superiors, some doctors and even the searched the web. I learned that they have different effect on people. It actually depends. So, I say you need to be informed first before taking diet pills.
