Does anyone have episodes waking up in the middle of the night feeling like you can't breathe and their heart is racing? This has happened to me on and off over the years. I'll get where I have months between episodes of this, while other times I have this happen several times in a week. Since I'm overly concerned about my health I have had many tests done: EKG, echocardiogram, stress test, holter monitors, event monitors (since I have palpitations too), gallbladder function test, sleep study. All have come back normal so no doctor knows why this is happening to me at night. Does anyone have this as an issue with anxiety? That is the only thing I can think of contributing to it even if I go to bed relaxed. It's actually been worse since starting this program. I'm towards the end of session 2 and I've had these episodes every night for the past week. I do have acid reflux too which is unresponsive to treatment.....I'm at the max of medications I can take but they don't help. I'm hoping if I take care of the anxiety/depression issues the reflux will lighten up if that's a contributing factor. I used to be a healthy person but since I gave birth to my 2nd child just over 3 years ago I seem to develop problem after problem.
