For over a decade I have LOVED caffeine, but when you drink caffeine it raises your cortisol , which just make weight gain increase , anxiety, heart rate , ect . HOWEVER there is good news , GREEN TEA does not , it actually does the opposite it helps you lose weight and keep you mind clear .
Both when I has the cushings tumor and in recovery and trying to balance my sodium levels , green tea all day till about 3pm .
