anxiety and stress
"After living most of my life with undiagnosed anxiety and thinking I was normal it wasn't till life got serious that panic attacks and severe anxiety took its  toll. After seeing many doctors etc one finally prescribed paroxetine and now life has never been as good. It took 2 weeks to build up in my system and it was like taking a fire extinguisher to the constant adrenaline hits to my stomach.  Definitely worth at try."
