Thanks everyone. Yeah, I used to have a love/hate relationship with the CPAP, but it wasn't long before it was a hate/hate relationship!
Frank, CPAP stands for Continuous Positive Air Pressure. It keeps the back of your airway open. BUT, it's like sleeping with a cat: it wakes you up a lot.
I'll let you know how it goes. Gotta be better than feeling drained all the time.
