sweet Pea, sorry to hear Melatonin didn't suit you, it works a treat for me although it does give me very vivid dreams.
As for insomnia, I've pretty much been there bought the t-shirt blah blah blah. I suffer badly with insomnia always have done.
Im constantly searching for something that will stop my mind racing and allow me to sleep., and stay asleep!

If you find something that works, be sure to post it on here!!

I too find alcohol unhelpful, although I go to sleep quicker after a tipple I wake up and stay awake at silly-o'clock every single time I dabble!

I also find alcohol a definite downer for me these days, always doom and gloom the next morning, so tend to avoid drinking as much as I used to.
(not a raging alcoholic by the way, just drank socially

)
