Of the same kinds, class, or nature

I generally stick to non-pseduphedrine stuff (like sudafed) and then I'll take a pain reliever like advil with it because I've never had a good reaction to it, but I needed something for the interview yesterday and the Aleve let me breathe. I was fine during the day, but the one I took at night gave me the worst bout of insomnia! I couldn't shut my brain off to sleep. It was horrible.

Advil wasn't doing much for me, I tried it on Monday.
