I've never heard of that, and I'm on EffexorCR 150mg a day.
I've been on Vicodin, Vicodin ES, Norco, Methadone, Dilaudid, Demorol, and never had an issue. I was on Dilaudid and Methadone in the hospital for a month straight with no issues. I take Vicodin and Norco (2x vicodin basically) as needed and never had an issue.
I've never even heard of an issue like that with Effexor. Maybe time to try and new Doc?
