I've only recently tried applying the TAG principles to my blood glucose management. This morning I decided to have a cup of decaf coffee and I used sugar-free hazelnut creamer and hazelnut flavored Splenda. I checked the labels carefully - or so I thought - and my BG was 98. An hr later my Dexcom is sending an alarm and I check it. I have the single arrow indicating a "rise". Checked my bg and it was 175 :( :( I sure don't have to drink flavored coffee but I still would like to know what I did wrong? Is it the caffeine, the artificial flavor or the phase of the moon??
