Yes but in its defense I have to say I drink 8 to 10 cups of tea in a 13 hour or so period and used 2 packs in each cup. That was apparently more than my system cold take for some reason and 'blamo' I actually made sure my things were in order because I thought I was a goner. I can't tell you how sick I really felt. My doctor said my heart was out of wack. I tried cutting out the tea and felt better. It was herbal tea and several different kinds so knew it wasn't the tea. Plus I put Splenda in my oatmeal or dry cereal and on and on and on...I'm pretty sure its okay in moderation but I won't touch it now. I tried real raw sugar and love it and its not bad for my diabetes at all either...my heart is fine and so am I.
