One possible reason for your not feeling drowsy after a full bottle of wine could be that over time your brain has developed some tolerance for alcohol. Other factors that may be implicated are, whether you had eaten something before having alcohol or not and how quickly you had the alcohol. Since you had the full bottle over a four hour period, your body got enough time to metabolise the alcohol. Difficulty in sleeping may be one of the earliest signs of alcohol withdrawal
. I would have been able to help you better if you had mentioned your usual alcohol intake and how it has changed over last few months. Also it is difficult to comment on your heart beat as you have not mentioned how much it is, but again, raised heart beat is common in alcohol withdrawal.
The symptoms are unlikely to be due to any infection as in that case you would have also had some fever
Hope this is of some help to you.
