My aunt reacts the same way. We're both recovering alcoholics and she'll go to the doctor, but then refutes everything the doctor says. I cut back on my caffeine because I noticed that it upset my stomach and made me extremely jittery if I drank more than 2 large cups a day. Have you tried chocolate? Or any other sort of sweet? I think my body craves sweets because the alcohol was full of so much sugar. I find eating sweets (whether fat free or not) curbs my desires. And it doesn't give me the jitters or a stomach ache. I wouldn't listen to those people, I would do what makes you feel comfortable. If curbing your caffeine intake is what's good for you, then go for it. I wouldn't know why other AA members get so weird about doctors. I mean The Big Book was written by a doctor.
