I have been having problems sleeping for several months where I will wake up 2 to 3 hours before I need to and had problem going back to sleep. Then I had chest discomfort for 2 weeks or so and was tested for heart attack. They said ekg, etc was normal.
I believe some of problem is acid reflux as Tums and Pepto help. I also feel bloated at times and can't sleep on either side due to discomfort. I will also gotten shaky a couple of times like I'm really cold.
