Sharp stomach pain/ache...

I have had a very sharp stomach pain/ache that happens in the middle of the night. It has happened to me twice now...once on Saturday nite after I got home from a halloween party where I had a glass of wine with 7up, 1 shot of patron, 5 glasses of just 7up and 2 bottles of water....then it happened again last nite(sunday) I had a soda with dinner and then 2 glasses of wine mixed with 7up. I rarely drink soda so I was thinking it is that but I have no clue now. I have read many of these forums and answers and I am unsure what it could be so any help is much appreciated....Also, I recked my dirtbike about 2 weeks and the handle bars went into my chest and stomach area. I went to the hospital a few day later and the said my ribs were very badly bruised and my liver was very unhappy (among a few other things arm, head, knees). Could this also have something to.do.with it because I have never had this problem until now and it was my first time having a lot of soda/alcohol since my crash. I know probably not a good idea but it honestly wasn't much in my opinion and its halloween....help please!
Thank You,
