And some board members have expressed concern not only about Mr. Musk's workload but also about his use of Ambien, two people familiar with the board said.
Tesla produced only slightly more than 100,000 vehicles a year ago and the company has been struggling to boost production of its Model 3, which is less expensive than its first models and could help expand Tesla's base.
That's the question that the nine board members of electric auto and solar panel maker Tesla Inc. must answer after Elon Musk, the company's impulsive leader, admitted to The New York Times that work is rattling his nerves in what he described as the most "difficult and painful year of my career".
Describing the past year as "excruciating" and "most painful year of career", Musk said that the things are a bit shaky since the tweet.
The 47-year-old said he sometimes did not leave the Tesla factory for three or four days straight and he had not taken off more than a week at a time since he was sick with malaria in 2001.
Musk boomeranged from laughter to tears during an interview with the NY Times.
But board members reportedly fear the drug contributes to Musk's eccentric social media posts and are concerned over his health and possible use of other recreational drugs. The board also said it hasn't even fully explored whether to go private. "The worst is over from a Tesla operational standpoint, but from a personal pain standpoint, the worst is yet to come". "You can love the company, you can love Musk and hate having him be the CEO at this point".
He has since said he is searching for funds for the effort.
Last week, Musk tweeted that he was "considering taking Tesla private at $420".

Now, Katie hopes to use her historic surgery to raise awareness about the lasting harms of suicide and the precious value of life. Gastman said that in his 27 years of training and practice this was one of the worst face traumas he'd ever seen.
"If you have anyone who can do a better job, please let me know", Musk told the Times. But I was not on weed, to be clear'.
Musk told The Times he wrote the tweet in his vehicle on the way to the airport, and no one reviewed it.
Musk is known for odd behavior and controversial statements, but investors have stuck with him and driven Tesla to a higher market value than General Motors.
On Thursday morning, Tripp tweeted pictures purporting to show damaged battery packs that were later installed in Tesla Model 3s, along with a list of VIN numbers to corroborate his claims.
"Weed is not helpful for productivity". "I wish there was a way to get nutrients without sitting down for a meal".
One of the plaintiffs, Kalman Isaacs, says Musk falsely claimed funding to take Tesla had been secured to "completely decimate" short-sellers betting against the company.
Adam Grossman, principal of Mayport Wealth Management in Newton, Massachusetts said he has avoided owning Tesla for clients except through indexes, partly to limit the risk of missing out on color Musk could share with a small circle.
That's one of the reasons the stock has fallen so much after soaring 11% on the day of his tweet.
The summary also says Hansen, "was told these tactics were specifically authorized by CEO Elon Musk", and implemented by the company's security team.
