I take it all the time because have a lung disorder. I much prefer the 400 mg. In fact, I don't like extended release in anything. For me at least, it's not extended release - it's just nothing after the first few hours. The 400 mg can be hard to find. The Walmart version is something like 88 cents a bottle for 15 tablets and Dollar Tree has it too.
