Am I reading too deep into this?

The guy I’m talking to just sent me a text 8 hours later telling me he couldn’t respond because he wasn’t feeling well and took medication. Mind you, we spoke hours ago before this , he didn’t mention feeling unwell or anything. I don’t know how to approach this situation, a little text letting me know they were heading to bed early because they weren’t feeling well could’ve went a long way. He was the one saying he wanted me to put in more effort and respond faster but can’t communicate when you’re going to be unavailable for multiple hours
