It all depends on what you ate and when. Having high BS levels tends to feel ok, but having them high all the time can cause organ damage. A one off is ok. If I ever have a bit too much to drink, it doesn't affect me, but I drink small amounts regularly. If you rarely drink, which is wise and I need to heed my own advice here, it will hit you harder suddenly drinking a whole bottle of wines worth, especially on an empty stomach. There are many factors to consider, your general health, your BS control levels, diet and eating patterns, time of the month, hours worked, stress factors, medication dosage and so on. Think about what was different from a normal day APART from the drink first and then compare WITH the wine. Is it a massive change? Sometimes if I've had a long day and have a post work pint, I make sure the train I catch terminates at Wolves. I'd hate to wake in Manchester, Edinburgh or Glasgow. I once got a Wolves terminator and fell asleep and woke up in Walsall after it had stopped and gone back through Birmingham and on to Walsall. That added 2 hours to my journey home and another half hour on the bus. If I'm tired on the way to the city centre I sit at the front of the bus and the drivers wake me when we get there, it's not very often. On the way home my stop is halfway, so I have to remain awake or I'll end up back in town. Lol. I hope you find an answer, maybe you didn't have a great nights sleep. I suffer from that, especially in warm weather. Good luck.
