HI Doc, I am 37, not obese but not fit either. No family history of anyone dying from heart disease before 50. I do suffer from anxiety and am on Lexapro but forget to take it some days. Yesterday afternoon, around 5pm I had a double shot expresso machiatto from starbucks and it kept me up last night. My heart felt like it was skipping beats every minute or so...and then I got anxious and felt like it got more frequent. I fell asleep at say 1:30am and felt ok this morning. I don t sleep well, stressed at work and drink a lot of coffee late at night sometimes. I tried to have small cup today and the same thing started happening to my heart. Do I need to cut out caffeine I guess? I feel ok now, after drinking a lot of water and it s not happening as often now.
