Try flossing. That “morning breath” is food that’s been sitting in your teeth all night. You’ll be amazed at the difference. 
I used to wake up and have the taste like I’ve been chewing on shitballs all night. Then I tried flossing and it changed my life. LifeProTip

I’m also convinced that a lot of people were never taught to brush/scrape their tongue before bed. Makes a world of difference.
