gastritis/duodenitis
"I can't even explain how horrible this headache is. It is 3:44am, and I can't sleep a wink because of the horrible pain I'm in. I've only just started this medication, yesterday, and it will be my last dose. It's Pantoprozole Sodium Extended release 40mg. When they say headache is a possible/common side effect, they weren't kidding. Migraine like pain. I will gladly take gastritis over this crap. Never, ever, ever, ever, ever, ever, ever, again. This sucks soooooo bad!!!"
