Pot and sleeping

So my bf works a night shift, 28 days straight then has 28 days off. So when he’s home he uses weed to “sleep” then usually has a nap at some point in the day. He’s been complaining, he’s been going to bed exhausted at like 10pm and waking up at like 3am, then being exhausted at 8/9am ... sleeping until 2pm then all over again. He’s also been home since early this year due to one thing or another.

Settle the argument. I say he needs to adjust by going awhile without the weed “sleep aid” and without the nap and just deal with being tired for a few days to get into a regular sleep pattern.

He, of course, says NOPE that has nothing to do with it.

LOL who’s right?
