Big hugs hon - it's really nasty.

DH had it last year, wound up in hospital for 4 days on oxygen due to not being able to breathe. He was a lot better semi-reclined to sleep rather than laying down, he said it took some of the pressure off his chest - so maybe look at sleeping in a recliner if you have one or propping yourself up on loads of pillows.

The docs also had him on ventolin for when it got really bad, but check with your doctor first - and take it easy! Get plenty of rest even if you aren't sleeping, plus eating a balanced diet with plenty of veggies.
