What's the longest you have ever stayed awake?

I am a zombie right now. My husband got called into work Saturday night at 5:30 and worked until 9am on Sunday. I feel so worried and guilty going to sleep while he's on the job. I slept one or two hours the whole night. I laid beside him after he got home until about 11 then cleaned the house. Last night I couldn't go to sleep until 2 and I have to be up at 6. My sleep schedule is all out of whack. 😩
