Hi everyone.
Hope mouse is enjoying Aberdovey.
kot - onwards and upwards!
gugg - I'm not a scientist, but as I understand it, the way any addictive substance works is, your brain is naturally set up to respond to chemicals that are present in the body, and it will also respond to chemicals you put into it, like alcohol or caffeine or whatever. But it adapts - if you keep putting in chemicals, it adapts to make this the 'normal' state. That's why you need more and more alcohol if you're drinking a lot, in order to get drunk: your brain is used to the effects and has to some extent normalized them. When you take the alcohol away, it's as if you are missing something that's become standard. Your brain has adapted to expect alcohol, and now it has to re-adapt - fast!
I think that's chemically why we crave it ... that's why normal people who drink a bottle of wine will be groaning the next day and sipping water, whereas some of us will be groaning but thinking 'hmm, a sneaky glass of white would just take the edge off this'.
I think there's also the psychological addiction. There's a site someone linked to on here over a year ago that explains it better than I can, but basically it was saying that human brains are very, very clever at filtering information and re-presenting it in a useful form.
If you're an alcoholic trying to stay sober, your brain is working against you to persuade you for its daily dose. So you say to yourself: I drink because I'm stressed! So long as I avoid stress, I'll be fine! And your brain then convinces you: yeah, but look! You had a rough day, you're feeling awful, look, you had a row with your partner - this counts as stress! You can drink!
Soon that turns into 'oh, no, you stubbed your toe - have a drink!' and you're back in that cycle of drinking and feeling guilty. Basically psychological addiction is like having a constant wrestling match with your own mind, and always having to remind yourself that you know these tricks your mind plays.
I'm sorry if that is useless and you wanted hard science with diagrams! Sure someone else can provide if so.
Oh, I am sooo sleepy babes ... I hate this bit feeling groggy all the time, I can't get anything done. Meh.
