My heartbeart has been throbbing in my head for over a week. So loud it is difficult to fall asleep. I feel like i am drinking plenty of fluids, however, my lips get very dry and swell if i dont guzzle water night and day. I have only had a couple hours of sleep each night. I am not a smoker, haven’t had alcohol since February 4,2018, do not do caffeine except a little green tea once in a while, am about 30 lbs overweight, even though i try to exercise a couple times a week - xc skiing and bike riding (haven’t exercised in two weeks because i feel so crummy with this heart palpitation). I have had this before when under high stress, and believe it is anxiety related. Any recommendations on how to calm this dowm? Thank you so much, Melanie
