When you are addicted to alcohol are called endless. When you try to quit, it has been said that the trigger condition can affect, but it may actually be 3 weeks before you take a drink of one incident. Delayed response.
You can have the urge to drink just by talking to someone on the phone, whatever you think, either to drink a story or just talk about drinking. You can get overwhelming motives by watching a movie where players are drinking or watching an advertisement for beer.
When you go outside the door, the power stations are endless. Driving past alcoholic beverages can give you a drink. Going down the alcohol or beer course in the grocery store, you may want to pour one. Seeing your friends with a drink can solve yourself. Even just visiting an institution where you have had drinks in the past will bring a urge to drink.
And that's when it's going well.
Any incident that provokes you or causing inconvenience may affect you. With a worsening situation, you put into what is "the use of" the alcohol committee and that's what you're going to have one.
It's even harder to stop drinking if you have a volatile relationship with a significant person or your work that causes you a lot of daily worsening. If you are in a social situation or in a situation that causes you a lot of inconvenience, then these circumstances can put you in a "dreaming" area.
Where does this prompt come from? You have decided one day you have had enough of it; You can not take it back, that's it. No more drinking. The problem with this is that you have developed physical addiction so that every cell in your body (especially your brain) is screaming "we do not!" Thus, your body kills literally when you leave. Length varies by person.
Any rehab agency or physiotherapist will tell you that physical addiction lasts only 72 hours. Any former alcoholic will tell you that physical addiction lasts a lot longer. A year minimum anyway, is closer to the truth.
Thus, the urgent will not stop for some time. For some drinking problems, it helps to know in advance what to expect. Knowing what to expect can sometimes make the trip a bit easier.
