When I lay down to go to sleep at night I usually lay on my stomach or my side. I know this sounds silly but just as I am about to finally go to sleep often I will feel like there is a fluid running up into my throat and even into my head if that is possible. Some times I scares me and I jump up to a racing pulse but now that I am so use to it, I am very rarely startled and just sit up with no abnormalties in my pulse.
I am 24 years old. I do not have any chest pains. I am not on any medications. Unfortunately I am a smoker. I smoke a pack every two days. I do not have any other problems except for when I am trying to sleep. All of activities are normal
