So glad to hear you are doing well and that the surgery sounds so promising.
Others have passed along great suggestions that will hopefully make it physically easier. As for emotional, here's how I coped (I was on bedrest when pregnant with my daughter for 21 weeks): Keep in mind that it is a finite amount of time and every day brings you closer to your goal. Two weeks laying on your face seems tortuous, but will be well worth it for the lifetime of sight you have ahead. Look forward to the time when you are free to walk around at will and try and avoid concentrating on the now.
Books on tape are your friends! and lots of pillows and gadgets to make it less stressful. And buddy, I'd be planning a fabulous vaca while I was at it!
Hang in there!
