Hi Heartfright,
I have Apnea myself and some of your symptoms sound familiar to me. I cannot, of course, tell you that you do or don't have apnea.
I would suggest that you make an appointment with your doctor and tell him/her exactly what you've said here. Ask for a sleep study and if the doc isn't prepared to help you demand that he/she does.
Having treatment for Apnea makes a huge difference in your life.
Hugs,
