Hey there remember what your doing this for. You will eventually be able to drink caffeine again and it will be tastier than ever when you do. It's worth the wait!
I was in the same boat. I would drink between 40-60 ounces of coffee a day. I knew I couldn't quit cold turkey so I cut down to one 8 ounce cup a morning. It gets me through and I'm not craving anymore. Never really had any withdrawals.
