I'm not personally on Vyvanse, but my 8 year old is. It works for him, but that doesn't mean it's a good fit for everyone. If you haven't started one I'd suggest starting a mood calendar/journal and keeping track of your moods to see if it is working.
I take Lamictal and find it very helpful. I take 200mg in the morning and 100mg at night.
I take Lamictal. It works well for stabilizing me. We had to up the dose a couple of times at the beginning until it worked. But I take Propranolol for anxiety and migraine prevention. I don't have adhd so can't comment on that part.
