Callie,
I'm so glad that his surgery got moved up to the 24th.
I can't imagine why they wouldn't give Don something to help him sleep. Sometimes all it takes is a low dose of an anti-anxiety med, like clonazepam, to help him sleep. When I was first diagnosed, I was a total mess. I couldn't stop my entire body from trembling. I was pregnant and the only person who would give me anything to help was the high-risk OB-GYN that took over my OB care when I was going through treatment. She said that I was "on a spitting dose", meaning that it was so small, not to worry. Only as I got closer to delivery, did I have to wean off of it and by that time, I was well on my way to recovery. This may be something you want to ask for again because Don is doing to need all the rest he can get and it's not fair to make someone suffer more than they already are.
Good luck to the both of you and thank you for the update.
xoxo,
Kerri
