My husband was at a sleep clinic for sleep aponea also last Thrusday, so I understand exactly how you feel! I didn't crate my dogs that night mainly for the company, but also because I couldn't lock the front door since he was coming home at 6:00am. DH decided to change the locks to more "secure" locks after we moved in....and lost the keys!
Since I wasn't planning on getting out of bed at 6:00 I left the door unlocked. Of course, if someone DID come in (and we live on a dirt road so it was very unlikely) they would have been killed by kisses from the dogs!
Just don't make the same mistake I did. At 1:00am, I was still wide awake. I had to work the next morning and knew I needed sleep, so I took a sleeping pill. NOT a good idea! Not only did I fall asleep after he left for work at 8:00 and woke up 10 minutes before I had to be at work, after I called to say I was running late and would be there as soon as I could, I fell asleep AGAIN! Needless to say, I ended up calling off work, and didn't completely wake up until around 3:00pm. I was still groggy but functional...barely.
TCS was a life saver and got my mind off of being there alone. But, I know...it's weird. Sending
for a good night sleep!
