How will your blood sugar levels be low? All the spirits/VKs/beers etc are loaded with sugar. I'm not saying you're wrong but I'd like an explanation.
For me:
- Plenty of water before you sleep and in the morning.
- Plenty of fruit/food on waking up. Vitamin C is essential in the breaking down of alcohol so drink plenty of fruit juice.
- AVOID paracetamol/caffeine as it puts more strain on the liver which is already struggling to recover.
- Light exercise, run early afternoon. Probably not the best idea to put your body through intense stress first thing in the morning.
- Alternatively, get up and go for a gentle walk.
Hangovers are also caused because you don't sleep properly when intoxicated and there's not much you can do to avoid that other than go back to bed
I was thinking of getting some fresh air, drinking some water and hoping my car hasn't been clamped where I left it.
