Members shared mixed experiences about how caffeine affects their diabetes, with the vast majority reporting no impact on blood sugar when drinking black coffee or unsweetened tea, though a few noted that coffee raised their glucose levels or caused other issues like heart palpitations or digestive upset. Several members emphasized the importance of drinking coffee without sugar and using alternatives like stevia or monk fruit, with many consuming multiple cups daily (ranging from 1 to 12 cups) without any negative effects on their A1C or daily readings. A recurring theme was that individual responses vary widely, so members encouraged each other to monitor their own body's reactions, with some switching to decaf to avoid sleep disruption or other side effects while others found that caffeine had no negative impact at all.
