nasal congestion
"I've had plugged ears from sinus congestion for two weeks. I took two doses every four hours of two tablets each and the congestion has finally cleared but I didn't realize that it would make for a sleepless jittery night and now a jittery morning with no appetite and mild nausea. Next time I would start with one tablet and see if that helps and make sure I had plenty of time before going to sleep."
