I can believe someone else had the same problems, I thought I was nuts. I used to drink around 6 cups and day. I gave it up cold turkey and for about a week, I had bad headaches, moody-ness, and a general sick feeling. It lasted about 6 days, until I broke down and had a cup. Since then (2 weeks ago), I have had only decaf, and I switched to herbal teas. I think the hardest part for me, was to break the coffee break syndrome. I was programmed to go buy that coffee at certain times during the day. Now I am just buying the tea or decaf. Give it about 2 weeks, I never thought I would be able to do it. Good luck, you will feel better. Alicia
