How to kick the coffee habit

I talked to my brother recently - who I always knew to pull all-night study sessions with a cup of strong black coffee - and he was saying he has a hard time sleeping if he drinks any caffeine after 4 p.m. I think most of us have run into this situation at some time or another. I have always loved coffee, but it was among the many things I chose to renounce during pregnancy and breastfeeding. I tried going decaf, but was concerned with the decaffeinating process - I realize the "Swiss Water" method is probably ok, but the thought of formaldehyde possibly entering my body scared me. I now drink herbal tea, but for a while I was really stuck on coffee. My husband and I were craving coffee about a year ago, and he went to Whole Foods to see what he could find. My husband asked an employee for suggestions, who saw my husband holding Teeccino in his hand and exclaimed, "Oh, you wanted ersatz coffee!" Since then, we enjoy an occasional cup of Teeccino for a special caffeine-free coffee treat.
