I don't think 1 or 2 cups a day would be too bad. But I'm no expert. :)
Here's a few ideas if you're looking to cut back:
1) Drink it weak. Half hot water/half hot coffee. Or half regular/half decaf.
2) REALLY enjoy that one cup. Make it a delicacy. Not sure how you drink it now, but if you get yourself some good beans, grind them, make the coffee, then sit and drink it, you'll get much more out of it than someone who just chugs it for the caffeine.
3) Find an alternative. There are some amazing teas out there. My husband and I are huge fans of Teavana. Also fans of apple cider, chai, and hot cocoa.
4) Drink espresso. Yes, it's true (mostly) that espresso has more caffeine than coffee, but it's more caffeine per ounce. A 6 oz latte has much less caffeine than a cup of coffee, and it's filling with the microfoam. We make these almost every morning.
Hope you find something you like!
