I'm not sure if this relates to anything I listed, but at times I'll get extremely nauseous, but never throw up. I just get that feeling that I'm going to, and it makes me feel so sick, that I can never sleep at night. For some reason, I'm only ever able to sleep during the day due to it. Never at night anymore. Its almost 9AM for me, and I still haven't slept because every time I lay down, I can hear my own heart beat, I get nauseous, my head starts to hurt, etc. It's something new every night. Only constant is the nausea. And I'm scared. Someone please help me. I think its either from my Acid Reflux or from the anxiety.
