Falling asleep on the couch every night

I have a terrible nighttime routine. Almost every night, I fall asleep on the couch at like 9 or 10 without doing anything I need to do for the night (clean up dinner, take the dog out, brush my teeth, etc). I live in a townhouse so my bedroom is upstairs, and when I’m falling asleep or am dead asleep, the last thing I want to do is completely wake myself up and do things and climb a flight of stairs. I’m trying to find a way to make this work for me, but I just can’t, and it’s making my life worse.

I could just go upstairs after dinner, but I don’t wanna lose the rest of my night because I know once I get in bed, I’m gonna fall asleep, and sometimes I still have stuff to do (plus my tv and hobbies are in the living room downstairs) and I have to take my dog out before bed. I’ve tried setting an alarm every night but I usually end up snoozing it because I’m too tired to get up (yes, defeating the purpose) or if I’m already asleep and don’t hear it, it just turns off after a certain amount of time anyway.

As you can imagine, I’m exhausted the next day from either getting up in the middle of the night to do all the stuff and move upstairs, constantly waking up and snoozing alarms all night, or sleeping uncomfortably on the couch. Is there anything I can do to train/push myself to have a better nighttime routine? Or any tips/tricks I can do to make something that works with my schedule and quirks? I thought this would be a good place to ask because time management and habit forming are hard for us. TIA!
