I wanted to post an update on my 7-year-old son Luke who started taking Vyvanse in early December. I'm happy to report that this medication seems to be working well and we even increased his dosage from 10 mg. to 20 mg. The experience with this drug is so much better than Focalin, which made him withdrawn, irritable and depressed. Since starting Vyvanse, we have seen his grades dramatically improve and his teacher says she can clearly see his ability to now focus in class. The best part is, Luke is still the funny, silly, loving boy we love so much! I'm so grateful that things seem to be looking up and am very grateful I found this forum to share experiences with other parents going through the same thing.
