Hi Sam.....it could be the effexor causing the D...I do remember having a much looser stool for a while after using it.
You could consider the Metamucil orange Smooth (not the sugar-free) and take it right after supper to start.
You do have to consider time of fibre and time of meds..etc. See which meal would be best.
