Not sure where to put this but this is my fav section so here will do. For the past few days I have been having trouble going to sleep. I start to get a feeling in my chest sort of like nervous butterflies feeling but not in my stomach. It's not painful in any way its just not comfortable, then I eventually (after 3hrs last night) I drift off to sleep then wake up like I am being shaken. Imagine if someone grabbed you by the arms and sake you from side to side, this is what it feels like. Then I drift off back to sleep. Any ideas? Anxiety?
