This last week or so things have been pretty scary at night. I am tired, have taken my meds, etc. but when I lay down some sort of anxiety immediately comes over me. I shift from side to side, throw the covers off, put them back on, sit on the side of the bed and takes deep breaths. A real uncomfortable feeling - almost as if I'm not getting enough air or something... Last night it was 2:00 before I slept any. This is new to me. Anyone else been doing this? Any suggestions?
