Husband Newly Diagnosed and Starting Vyvanse

My husband has been newly diagnosed with ADHD. This is no surprise to me. We have been married 15 years. I am running out of patience.

He as started Vyvanse and is titrating up to 60 mg per day. He has been on the medication for only five days so far. He says that he does not notice any difference in his attentiveness. I am noticing that he has become even more angry and difficult to be around. Is it possible that his body is just getting used to this drug? Might these side effects go away? How long until he should see any positive changes?

I have so many questions, and I am just tired of constantly having my feelings hurt by the one who supposedly loves me. I don't feel very loved and haven't for quite some time.
