Expert writing Tips
Best practice
Use the phrase "sleep well" instead of "sleep good" for correct grammar. "Well" is an adverb, which is what's needed to modify the verb "sleep".
Common error
Avoid using "good" when you need an adverb. Remember that "good" is an adjective, describing a noun, while "well" is an adverb, describing a verb. So, while you can say "a good night's sleep", you should say "sleep well".
