Sorry the nights aren't kind to you. There is nothing worse than being awake and not being able to go back to sleep. The breathing part worries me though. See I have insomnia and sleep apenea and I stop breathing two to five times a week. It is very scary. You wake up gasping for air and it's not there. I use my inhailer and hope that works. Sleep disorders can be very dangerous. I can basically know if I am going to have a bad night if I have taken all my meds and I am not asleep by 11 PM. Sounds like you are hyperventelating. It may be a good idea to give your reg. doc a "heads up" on this. If it helps, I can relate!
