The whole reason I started drinking was because I had really bad insomnia. Over time, the thought of not being able to sleep without booze for me became for powerful than the original insomnia. I was completely terrified of not drinking for a night because I 'knew' I wouldn't sleep at all.
Eventually I got to my wits end, said sod it and just went for it. It took about a week or so of restless nights but at the moment (touches wood) i'm sleeping really well without any aids. It feels bloody marvelous to wake up knowing that as well.
Best of luck to you
