I have been having heart burn, with acid reflux for 4 days now, it tastes so bitter, and I can t lay down to go to sleep, as it hurts so bad. Should I go to the emergency room, because I can t sleep it bothers me so much, the bitter stuff comes up into my throat and burns my throat, therefore I can t sleep tonight. I ve taken Tums, baking soda and water, soda crackers, and Prilosec, nothing is helping me and I m so tired, could this be a symptom of any serious condition??
