Three questions kill most of the confidence in a thread like this: sample size, blinding, who paid.

Sleep first. Bad night, bad day, more symptoms. Fix that before changing anything else.

You have two changes at once here. You cannot attribute anything until one of them moves.

I would take the narrow conclusion. Broad ones are more interesting and less true.
