Hi All, Last night, browsing through the Mtx leaflet 🙄 I noticed that 'large amounts ' of coffee and black tea should be avoided. Can anyone shed any further light on this- like how much is a 'large amount' and what's the reason for the caution? I ask not because I think I drink a lot (2-3 a day?) but in order to understand what effect drinking any might be having. Many thanks.
