One thing that wine does is to irritate the bladder and make you pee more often, and with more acid urine. Unless you drink lots of water you are going to feel worse, not only in your head and stomach, but also in your poor bladder, which has enough to contend with.
Put away the wine bottle and drink at least a glass of water right now, and get yourself something to eat. Then, after each time you go for a pee, drink another glass of water to replace what the alcohol has wrung out of your kidneys (which it had stimulated to remove water from your bloodstream and make you dehydrated), and continue doing that all night, and into tomorrow.
As soon as you can, do as DollyD suggested, and get an appointment with your GP to discuss this emptyness you feel.
