Hi Mary, I would prefer to use the complete organic coffee as that doesn't bother me. If there is a reason for you to not have caffeine then use the decaf. It is important to relieve yourself with water first. Then I implant a cup to 2 cups so I can hold it for 20 minutes. I am finding that it helps stop many of the herx responces. Remember to drink 1 quart of water for every 40 lbs of body weight. I also feel Cascara is a tonic and builds the bowels if used a few times a week during detox. MW
