A few question around melatonin..?

1. how long before i go 2 sleep should i take melatonin, sometimes it works and i win all sleepy and sleep real good but other times, i can't drop asleep and i wake up in the middle of the night and enjoy weird dreams?
2. is it ok to take melatonin (pill) if i'm under 18?
3. if i save taking melatonin will i eventually become sorta immune to it?

thanks =)
Answers:
Just a word of caution regarding Melatonin.

The sister of a friend used to bring this. It apparently triggered a Rheumatoid Arthritis response and she became quite disabled with it.

In her overnight case there is a family history of the condition, so I can't say that everyone will own the same reaction.
20 to 40 minutes. It depends.

Yes.

Yes, so only give somebody a lift it every few nights, or take it to, as the bottle says, "Promote regular sleep pattern."
