How long is spaghetti good for in the refrigerator?

I've stored cooked pasta in the refrigerator for up to 3 days with no problem. Our leftover pasta never lasts longer than that! If it's a small amount, just mix sauce and pasta together and store in an air-tight container. If a larger amount, I put sauce and pasta in separate air-tight containers. When I reheat it, I put a little butter in a no stick saute pan and add pasta with some sauce until hot. Don't reheat more than you can eat at one time. If it's reheated more than once, it doesn't taste too good.
