Since how long has he been doing this? And who told him to take all these pills? Has he beeen taking then by himself or were they prescribed to him?

I would say your friend is a victim of the American psycho phenomenon ... You know... someone who must o.d. on every performance enhancing vitamin or must subscribe to every fly by the minute secret to success guide...

Just like young women feel the pressure to be thin... men feel the need to suceed... but because men are supposedly strong enough... there is not a lot of media hype around it... I would say he is a victim of the Homer Simpson and Ted Bundy era...

Men are so afraid of being the loser they will do anything to succeed... If your friend is boasting about his vitamin abuse... I suggest you be his friend and accept him for who he is... DO NOT try and help him... he doesn't need any help... just be his friend and accept him for who he is... insecurities and all...
