I have been taking Vyvanse for over 3 years now, 1 60 mg tablet daily, however they believe it has something to do with my blood pressure being high now. Im 40 years old and this is the only thing that I have been able to try and not feel myself after taking, and I have never had a hard crash after taking it. It was actually GOD sent... So I stopped taking it and now I can tell the difference and struggle a lot daily. Does anybody know of anything that I can take as an alternative or something even natural to help me somewhat?
