2 week you would not notice a withdrawal, because the med would not be rooted to your senses in that short time, its years on 300mg that you get world war 3 . I have a e mail friend who was with me in the VENLAFAXINE ORG group and he still takes 150mg to the day , he has no weight gain and is sexually great so it effects people any sort of way, he had a brief relapse and they added Mirtizapine and he hammered weight on, a brief and depression helping time he came off the Mirtizapine and is doing well for years on venlafaxine and has no plans to give it up. JUST because you feel well don't mean you better he knows that.
