Currently trying Melissa Dream but have been suffering insomnia for 18 months and no closer to a solution.
I do recommend sleep podcasts from the Mental Health Foundation (they're free) One of them has a vairy sexy sounding Scottish man 
In the last year, I have had: (prescription)
seroxat
mirtazapine
prozac
mirtazapine (again)
valium
sertraline
sertraline and mirtazapine
and tried (non-prescription):
herbal teas (valerian, hops)
cherry juice (until I found out that study was funded by the Cherry Juice manufacturers
)
melissa (tablets or teas)
promethazine (an anti-histamine)
still to try (depends how desperate I get):
buspirone or pregabalin
melatonin is supposed to be a natural sleep aid which works well, but you can't get it in the UK except on t'internet
Sorry not to be of more help. Of all the above, I think the podcasts helped the most.
