I was almost asleep when all the sudden I get a rush of nausea and THINK im going to get sick.. Now after already taking 1 klonopin I have heartburn. It scares me so much... I dont want to V*... Starting to think that my anxiety is making my stomach hurt and giving me heartburn. Is this possible??? I know my anxiety causes "nausea" but can it also give me heartburn? Ughhh this is so frustrating!!! I need to find something other than klonopin to help me at night when there are not many distractions w the pressure to go to sleep! Im going to start reading THRIVE hoping it can help me because I am so sick of this terror. Please help if ur up![]()
