Greetings!
I was diagnosed a few months back and I’ve gotten on Vyvance 20mg to great effect. I’m not perfect, but much better.
However I do find that my focus wanes in the evening when I want to kick back and practice a hobby like drawing or music, I can’t sit down and just do it.
If anyone has advice or experience that might help, I’d be very grateful.
Talk to your doctor, but the simple answer is to take more. Vyvanse has a half life of about 12 hours, so if you take it in the morning then by evening the medicine is starting to heavily breakdown. It’s pretty common for people to take more at lunchtime to get them through the evening for that reason.
