While teenager is right, generally, 3 cups over a whole day is not a bad thing. Some studies say that (I really read this in the NY Daily News) Ashkenazi women who drink 3 cups a day have a 10% LESS chance of getting breast cancer. Ashkenazic women who drank over 5 cups a day have a 50% less chance.
Personally, while I drink about 3-5 cups a day, the coffee I drink at home is only 50% caffein. I buy a pound of regular and a pound of decaf and mix it. I don’t like the feeling I get otherwise if I stop drinking coffee. Also, before a fast you should ease up on your caffein or you will get withdrawal symptems.
Of course, if you get shaky, CUT BACK! Or just drink decaf.
Hmm. I think I will have anouther cup now. 🙂
