Anxiety
"I have been taking Effexor XR for about 8 years after suffering a serious mental breakdown. This medicine has given me back my life.  Having said that the UK government have recently told all doctors to prescribe the generic version. THERE IS A HUGE DIFFERENCE, I began suffering terrible headaches, and anxiety again. After speaking to my Consultant Psychiatrist I am now back on Effexor with all the nasty symptoms gone. There really is no substitute for the real thing."
