For the record, since I am on a mix of concerta and effexor, effexor alone does nothing to alleviate my symptoms (at the 150mg dosage). Although for me the adhd medication is no problem. It is actually effexor that torments me, because I have extreme withdrawal symptoms if I go even one day without it.
Effector is for dépression not ADHD. Do you get brain zap when you miss a dose ? Other medications don't have this problem, at least for many of not most people
Or maybe venlafaxine is to counteract any anxiety that the upper may cause. Well that's the theory my doctor had anyway. (I took venlafaxine with ADHD meds because of this)
