Few weeks ago I got sick and took a bit of Nyquil and found out that it repeatedly threw me out of ketosis!I didn't realize that Nyquil contains a good amount of carbs!You can read more of my experience here:http://bjjcaveman.com/2013/12/07/nyquil-ketosis-dont-mix/The bottom line is... if you're trying to stay in ketosis... avoid Nyquil!

Actually you only need to avoid liquid Nyquil. HFCS is added for taste. The Nyquil capsules do not have the HFCS or the carb content (capsules have zero carbs). So just avoid the liquid, but the capsules are fine.
I posted something similar about Zzzquil a while back and how mad I was at myself when I realized there was HFCS in the ingredients. Pill form, as already mentioned, still seems like a reasonable alternative.
