Hi Jodie,
I was banded 1 week ago and am also on Efexor XR 150mg.
I haven't had a problem taking mine yet, they are going down okay at the moment, but then again I haven't had a fill yet.
They are also working fine, I don't know about you, but on the few stupid occasions when I haven't taken them (pre op), I get a jumpy feeling in my head. So far this hasn't happened so thats why I am assuming they're absorbing fine in my system.
Hope this helps and good luck with your op.
