If I get steamed I'm a bit heady in the morning but a good fry up seems to sort the job. Doesn't matter whether I eat/drink before going to bed either. Usually too pissed to manage that anyway.
I tend to be worse if I go out and have 4-6 pints of bitter as opposed to a skin full. Vodka does not affect me the following morning, used to drink bottle or so a night at one stage so I'm kinda amune to it
Whisky or brandy stuff me up big time though even though I love em.
