How long do the sypmtoms of alcohol withdrawal last?

I've been drinking a lot for the last 8 months since my husband left me, at least 1 bottle of wine per night and much more on the weekends if I am alone. I came to a realisation on Monday when I woke up on the floor, freezing cold, not washed since Saturday morning that I need to stop, I have not had a drink since Sunday night, the shaking has stopped (mostly) but I cannot fall asleep and have night sweats/shivers which wake me up when I eventually do drop off to sleep in the early hours. I have no GP and my working hours make it impossible for me to seek medical help, can anyone advise how long it took them to over come similar symptoms or so. I am determined, I have resisted all urges to buy alcohol when I would normally back down. I know I am not the only one out there to struggle with alcohol abuse and would really appreciate some advice from those who have been through the same experiences.
