Running Twitter has been "quite painful" and "a rollercoaster", Elon Musk has said.
Things are going "reasonably well", Mr Musk told the BBC, stating that usage of the site is up and "the site works".
The workload means that "I sometimes sleep in the office", he said, adding that he has a spot on a couch in a library "that nobody goes to".
And he also addressed his sometimes controversial tweets saying: "Have I shot myself in the foot with tweets multiple times? Yes."
"I think I should not tweet after 3am," he added.
It has been "really quite a stressful situation over the last several months", he added, but said he still felt that buying the company was the right thing to do.
"We're trying to be accurate," he said.
"I actually do have a lot of respect for the BBC," he added, stating that the interview was "a good opportunity to ask some questions" and "to get some feedback on what we should be doing different".
