I have been going round and round trying to figure out my heart palpitations trying not to give up caffeine but I have had the most success on the days I have cut back on caffeine severely. If I could come up with a pattern it seems that the pattern is that I cannot have caffeine early in the morning without having any food. It seems that if I have caffeine after 2 PM and after I have eaten, it doesn't trigger palpitations. But still..it has to be moderate amounts. like under 100mg.

The theory at the moment is that my levels of cortisol has risen. I just had a saliva hormone test and both the early morning and late morning cortisol came back high. The early morning value was prior to having any caffeine. So if I have a large caffeine drink in the morning before eating... it triples or quadruples the amount of cortisol in me for most of the day. I am not even sure that the high cortisol doesn't cause me to get "stuck" in a high anxiety mode.

I am attempting to give up caffeine but I have LITERALLY gotten up ever day since the age of 14 and had a cup of coffee. Usually not eating for about 1 hour. This morning I cut the cup in 1/2 and I still had heart palpitations but, I got so sleepy I had to take a nap and after that nap.. I had zero palpitations.
