Buggi, your experience is very similar to mine and mine came to head this summer. A blessing in disgiuse I think 'cos at least I'm getting help now.
Elmer, as the last pages have demonstrated, you are by no means on your own here. I, like you, am dependant on alcohol. I can go all day without one, but anytime after six pm, well, I'm constantly fighting the cravings (and usually losing). With me it's cider.
May I suggest a good book on the subject of stress related depression. It's called 'depressive illness curse of the strong'. About six quid from Amazon, it's not a heavy read and I've found it very helpful.
Good luck mate.
