First time having Baileys and it does not taste like 17% alcohol. But it tastes good enough to get drunk before learning for exams in the next weeks

Just got a bottle of baileys as a gift for acing my "end of high school" exams. I never had my own bottle before. How do you store these things? It has milk in it so I might want to put it in the fridge, but only if otherwise it's good for less than a week, because everyone else in the family also loves it so in the fridge it'll be empty within a week.
