Black or green teas or a mix of both is a nice change of pace, especially after drinking pots of strong coffee or what I call, " Rocket fuel. " Tea along with some nice music before bed can be very relaxing. Coffee that is spruced up with a pinch of salt and some Irish Whiskey can be nice too.
The gourmet blends of coffee are ok and can be a nice change of pace as well but it's hard to beat a fresh cup of well made, basic coffee.
