I would not suggest using anti-depressants if they weren't prescribed to you by a doctor. There are simple reasons for this, but I like to call them common sense:

1. You don't know how fucked up your friend REALLY is, so you don't know how strong this shit is.
2. Assuming it says on the box 'NOT STRONG. TAKE AS MANY AS YOU WANT'. Do you really know what effect it will have on YOUR body? Are you allergic to something?
3. Anti-depressants are more dangerous than suicide. It is not similar to ABC gum (Already been chewed). You can't share with your friends and you shouldn't.


Do you see what I'm getting at here? Rather get your own prescription - that way you'll get the perfect drug for you, first time, every time.
