No kids. I do have emergency paging and downed server / PROD to deal with 24/7, not the same as kids, but wake-disrupting all the same.
There is rarely something urgent enough to prevent urinating in the morning, and being thirsty after waking up is typcially a no go either. If prod is down maybe I'll eval first, but humans need out and in of water. I'm not going to urinate on the floor, and I'm not going to sit dehydrated and parched mouth for long either.
So wake, urinate, drink and vitamins are in that too.
My vitamins are in the bathroom, and it takes less than 10 seconds to consume them.
