good for you, the first 3 days are the hardest. i cut caffine cold turkey and had terrible headaches, i added half of a cup of coffee back for a couple days and when i quit again, no headache... also i didn't sleep well the first week, so hungry at bed time. i found a ts of peanut butter and a sip of skim milk helped me alot. now it's all liquids and only clear liquids tomorrow.. surgery monday morning!!
