Has anyone used nyquil as a temporary/long term sleep aid?

Has anyone used nyquil in regular or larger than regular doses to aid in sleep before that could elaborate on their experience? How much is too much for you? I’m aware it can have long term repercussions on your liver, but I’m of the impression its no worse than a few drinks… can anyone clarify? I haven’t had a good nights rest in 2 weeks without the aid of at least 3 doses of nyquil… and I’m wondering if I may be better off getting a legit sleep aid. I’d been avoiding it so far because of cost and their highly addictive nature.
