Has anyone here tried taking melatonin?  Good, bad, indifferent?

A friend swears she has not had a migraine in the three months or so that she\'s been taking it.  She\'s also sleeping really well.  I\'m going to give it a try.

It\'s way too early to say if it\'s going to help with my migraines, but I am noticing an improvement in my sleep already.       After some wild nightmares the first night - could be unrelated - I\'ve been sleeping fairly soundly for the past few nights.  And I\'ve been falling asleep much more easily.  Those things alone might help with my migraine situation.
