Last weekend I was away with a friend. On Friday we had a couple of pints of beer in the afternoon watching a rally and shared a bottle of wine with dinner.
The following evening we didn't drink during the day, but shared a bottle of wine with dinner and had a cocktail instead of pudding.
I had a much worse hangover on the Saturday morning. On Sunday I felt a bit jaded/tired but no headache or other symptoms.
I'm not a regular drinker so both evenings were enough for me to be quite tipsy, but if anything I'd have expected to feel worse after the cocktail evening, as the alcohol was consumed more quickly.
