If when you lie down at night you can't breathe, you need to get to the hospital now!! It sounds like you are going into congestive heart failure
. this is not funny. I should know, I've have had heart failure for the last 10 years, so I know the symptoms and it has nothing to do with your weight. The fact that you had 2 strokes at 5 lets me know that you have some kind of cardio issue. Get to the emergency room now!!
