Killing me softly symptoms and conditions

Um I started taking Yasmin a month before I went to college, so I've been on it for about 2ish years now. I would say I have a lower sex drive, but I don't know if it's birth control or just me getting a little older. Other than that no problems, but I also started getting horrible hangovers when I started college too, which didn't ever happen before. I was wondering if anyone had notice that Yasmin and alcohol may cause severe stomach issues or if it just means as I got older my hangovers got WAYYYYY worse. I mean it's not just a normal hangover, my stomach hurts so bad I can't get out of bed. And it's not because I started drinking more in college, I would say I easily drink less now and no matter if I have 2 drinks or 10 I feel the exact same.
