This isn't insomnia but I can't sleep because I have a **** of a cold. If I lie down for too long I start coughing and my chest gets really tight which just ****s with my asthma. It's pretty hard to fall asleep when you can't breathe... well maybe not hard to fall asleep but if your ever planning on waking up again it's not very easy I hate this, I havn't had a good nights sleep all week.
