Hi widgets -

You don't say if there is a history of Asthma in your family or if you have any allergies. Either of these could be part of the problem for you. OurLadysTears also has good advice. You could have Obstructive Sleep Apnea, or it could be reflux from your stomach. I would talk to your doctor to get his ideas. In the meantime, try not eating in the evenings - especially for a couple hours before bedtime and see if that makes any difference for you.

I hope you find the cause of your breathing difficulty and start to feel better soon.
