If this just came on suddenly, most likely culprit is stress. If this is the case, then it should diminish as whatever stress you have subsides. It can also be caused by other things, including sleep apnea. Hopefully, the issue will pass. If it persists for an extended period, it would probably be beneficial to talk to a sleep doc. They can help diagnose the cause and find treatments to help resolve it.
