My 39 yr. old boyfriend was recently diagnosed ADD. He began Vyvanse 20 mg. 6weeks ago, and has been at 40 mg. for the last 2.5 weeks. It doesn't seem to be helping. He still has all his ADD symptoms but with the now added "Speediness", irritation, aggitation and clumpsiness. I know that finding the right dose is important, but increasing to 50 mg, seems like it will make the negative stuff worse??? Please help!!
