Once a day I take Vyvanse 70mg, Bupropion hcl er (xl) 300mg, Venlafaxine hcl er 150mg, the 3 have helped to some degree with my depression, but I still struggle. Dr wants to start me on Viibryd, working up to 40mg and gradually take me off venlafaxine. However, I start a new job 3/17/14 & I don't want to "wig-out" because of cutting back on the venlafaxine. Can I take the Viibryd without cutting back on the venlafaxine until I am settled in the job, which may take 3 to 6 months?
