Happens to me most nights wake up around 3am or so violently nauseated, heart pounds, cold sweat. 99.99% of the time its my anxiety flaring up. I have found if i get up out a bed take an anxiety pill and some ginger root pills i can get the feeling to go away. Its sucks, and i feel your pain honey!!! Hope it gets better soon for you...Just know your not alone! How are you feeling today?
