For me it was similar, but I think it was more about a lack of a natural friction. Normally when coding there was the "hit" of seeing something work, but the actually planning/coding/debugging would eventually wear me out, so I'd stop for the day. Now it can all just be endless "hit" of success and nothing that makes me feel tired or annoyed.

The reason I believe this is because I recently went through a really annoying battle with Claude trying to get it to stop being so strict with its sandbox. I wanted it to simply load some sanitized text from a source online, and it just would not do it. The sessions when I was sorting that out were so much easier to stop and moderate than the ones where everything just kept flowing effortlessly.
