5 Day notice or something else for someone with year lease

[Alexis Zion]

Hey Folks

One of my tenants who has paid regularly for the past 4 months suddenly did not pay.  Is it best to serve him a 5 day notice or is there a better notice to give.  

We called and he says he is waiting for is disability to come.  But Last week he said the payment was going to be this week...Blah Blah Blah

What do you guys recommend ?
