I've been on bupropion xl 300mg for 7 years and it has truly changed my life. I used to have very severe Seasonal Affective Disorder and social anxiety, both of which have been all but cured with the medication. However, I have also struggled with ADD my entire life and now, finally, at 44, I have sought treatment for that as well. I was prescribed methylphenidate ER-LA 20mg. I am trying to determine the best strategy for taking these pills.
