The painkiller is Tylenol.

Things like Geborin have been heavily advertised for a long time, but I haven't used them.

Recently, I tried TerraFlu after seeing its advertisement, but since it's mixed with water, I felt a slight nausea.

And I’m not sure if my memory is correct, but isn’t Teraflu just the same ingredient as Tylenol?

They say that just dissolving it in water to take it results in faster absorption.

It seems that Tylenol also worked immediately, about 30 minutes after taking it during severe migraines in the past.

When I was a high school senior several decades ago, I used to have neurogenic migraines that would cause me pain every day at 2 PM.

I took Tylenol immediately and somehow managed to endure. I think I took it almost every day for a few months.

Because I remember that, I know that Tylenol is a safe and non-addictive medication.
