Nyquil

[brake]

I took Nyquil the day before yesterday because I was feeling sick and I wanted to knock out. It helped with falling asleep but it made my visuals WAY worse before sleeping and during the next day. Has anyone else experienced this?

Nyquil contains dextromethorphan which people use to trip in higher doses, so I can definitely see how it would worsen your visuals. I would advise against taking it again.

Yeah I`m definitely going to stay away from it from now on.

Sorry to hear that you've had an unpleasant experience, this is what kinda pushes my away from taking substances as I don't want to indefinitely increase the severity of my symptoms.

When exceeding label-specified maximum dosages, dextromethorphan acts as a dissociative hallucinogen. Its mechanism of action is via multiple effects, including actions as a nonselective serotonin reuptake inhibitor^[3] and a sigma-1 receptor agonist.^[4][5] The major metabolite of DXM, dextrorphan, also acts as an NMDA receptor antagonist. In high doses this produces effects similar to, yet distinct from, the dissociative states created by other dissociative anaesthetic such as ketamine andphencyclidine.^[6] As well, the metabolite 3-methoxymorphinan of dextrorphan (thus a second-level metabolite of DXM) produces local anesthetic effects in rats with potency above dextrorphan, but below that of DXM

And with HPPD just taking the recommended dose is enough!
