Can I be acetylcholine deficient from using zzzquil 6 nights in a row?

I have been going through some sleep anxiety and experiencing sleep deprivation so I decided to use zzzquil to get some sleep. It wasn’t deep sleep however, and I didn’t dream when I used it. The drug affects me really strongly, I only took half a dose ( 15ml) each time, but I felt extremely drowsy for 12+ hours after. Last night I didn’t take it but my sleep feels the same and I feel foggy headed and forgetful. Are these lingering side effects, and should I take supplements?
