I had a glass of Cabernet 2006 at about 10 pm yesterday and it left me sleepless... is that a normal reaction?!
Answers: It's funny, red wine sometimes keeps me up too. As I understand it, the tannins and alcohol in the wine increase bloodflow, which could wake you up. Take too much, the alcohol takes over and knocks you out, but with just a glass I have similar symptoms.
Not normal but not too shocking either. I hope you have slept by now. If not someone drugged you, and not in a fun way.
Drinking alcohol interferes with your sleep cycle. Even though some people pass out after drinking, it isn't quality sleep. In your case it prevented you from getting to sleep at all. Totally normal.
