"i was prescribed effexor xr about 2 years after my mom passed away and it was the like the miracle drug for me.  then about 9 months ago i received the generic substitute for effexor (venlafaxine) and i had this debilitating nausea and threw up every single time i took it.  feeling this daily wiped me out and it caused problems for me at both of jobs.  i am highly upset about this change and want my effexor back.  i hear that i am not the only one this generic &quot;substitute&quot; has affected this way."
