Withdrawl symptoms can take up to 24 hours from the time of your last drink to manifest. Sometimes longer. From personal experience, i found that my severe symptoms lasted for about 5 days and i didn't feel quite right for nearly two weeks. Last time i sobered up i got my rear in gear and got to an AA meeting as soon as i could hold down water. Feeling less alone made the withdrawls a lot easier to deal with as did just getting out of the house. Seeing a doctor is important even though you're not having withdrawl symptoms. You've been abusing your body for a long time and you need to get a baseline read on your health. Start taking a multivitamin and be sure to stay hydrated. Don't poopoo the doctor and AA thing. There's a reason a lot of us SOBER posters recommend it. We might know something.
