I am trying to figure out why a CVS Multi-Symptom Nighttime cold formula (generic NyQuil) is having a stimulant effect for me.
First time using this medication. I took the regular recommended dose at 11pm. I was out by 11:30 and slept soundly. I woke up wired at 6:30am. This wired effect continued all day until around 7pm (20 hours).
I recognized the feeling as the same hard to describe feeling I got when I took Ritalin as a very young boy, 35 years ago. It's a very jittery feeling that keeps me moving. For the first time in quite awhile I stayed awake all day, even during evening TV time (the family took notice).
This medication doesn't seem to have any active ingredients that should cause this. Especially since it had a very effective sedative effect.
The regular dose I took contained:
Acetaminophen (650mg)
Dextromethorphan (30mg)
Doxylamine Succinate (12.5mg)
I don't mind the effect, but if this is something that isn't supposed to be happening, perhaps I should avoid it.
