Wellbutrin for ADHD'ers: Going from XL to SR

Was on 300xl for adhd and mood, saw it helped but felt 450xl would benefit more. The psych said 300 was the absolute max (I call bs, I know a lot of y’all are on 450 and even one guy on here is on 600!!) anyway, after I mentioned the different areas of my life it was helping in he agreed to do 200SR x2 a day....
