Sleep can be strange. I recall waking up at 4am every day for about 2 months. Upon waking it was an instant slap in the face of what had happened. After a few hours of hangover all was well. I recommend a gym membership if you don't have one.
Regarding the kids, if there are no temporary orders get possession as much as possible This is for them as well as you. Only use texts or emails to discuss this and make sure to note anytime she declines your wishes to see them. I have heard stories of one parent trying to hoard the kids in order to get preferential custody arrangement. Remind her of the BB tournament as well. That's not fair to the kid if he/she was hoping to play.
