re: Doctors/Experts of the OT. Realistic long term effects of Adderol or Vyvance?

I would encourage you to try to do without. Practically no drug is designed to be totally safe and benign for your entire life. Much of the drug's effects are mild, but many people function quite differently (from a personality standpoint) on it. This may be undesirable to you, in which case coming off may be a good thing for you. As far as withdrawals are concerned, talk with your doc who is prescribing it before you come off. In all likelihood, you could probably stop it with little/no effects, but not knowing what dose you're on or you at all, it's always better to talk to a professional who knows you about starting or stopping medicine.
