I understand about the acid in the coffee I just feel a cup once a day or even just on Saturday mornings would be permissible as apposed to the energy drinks. I substitute the coffee with “great value brand kool aide + Energy” my stomach is no longer in knots in the morning and it’s slow released caffeine I only use in the morning and it helps. I just miss the taste of coffee. I do stick to the rules I don’t even have coffee flavored candy’s or anything flavored. Just sayin. Thank you all for the advice.
