Using "neither" without "and" in a sentence

Is it grammatically correct to combine two negative ideas into one sentence and then start the second part with “neither”, like, "I don’t usually wake up at 6 a.m., neither do I like to wake up at 5 a.m.”?


Solution 1:

It is grammatical. But it is preferable to remove the comma splice: replace the comma with a semicolon or a period.
