Moose Loose aboot the Hoose 
OK, in no particular order... Sleeping good sleep starts with a good routine, relaxing warm (not hot) bath, gentle stretching (yoga-ish / taichi), warm drink (warm milk is very good but I hate it, and pineapple or banana also have sleep inducing ingredients), restful activity (reading, writing a diary etc), dark room (not too hot), perhaps a lavender spray on your pillow, some gentle meditation, perhaps an orgasm. No tea, coffee, or stimulating activity (TV, strenuous exercise, computer games). Herbal nytol is good. Non-herbal remedies often include anti-histamines, and they certainly leave me feeling horribly groggy the next day.
Next sex or more accurately sober sex. In my first marriage I had a very bad relationship between alcohol and unwanted sex. It is very, very good when those links are broken. For me sober sex is more intimate, is more sensual (I guess because I can feel things more), and involves much, much more kissing - mmmmmmm.
Next underlying issues I think that the evidence is that alcohol as a drug is not SO addictive that our alcohol problems result just from drinking too much, and there is usualy some emotional need that we are temporarily soothing by using alcohol. It may be lack of self confidence, fear of intimacy, not being able to deal with anxiety, being a bit 'bored/depressed' and looking for a stimulant, or many, many others. For me alcohol just became my habitual way of dealing with things. So without a drink - yes I am having to find new ways of dealing with things and I am having to face some uncomfortable facets of myself. But, NONE of them are as uncomfortable or difficult as facing the fact that I am an alcoholic, and none of them are so bad that it is worth ruining my life for.
Probably lots of other things I'd like to say, but I'll need to go an re-read the thread...
