Suggestion: Take the Vyvanse earlier in the day. Vyvanse can last quite a while (I've gotten 13 hours out of it) so taking it at 1pm is probably just too late in the day.

I take 70mg of Vyvanse whenever I wake up and it takes 40 minutes to an hour to kick in. I will say that I have a self-set rule that if I don't take it by 10am that I won't take it that day otherwise I'll struggle to fall asleep that night.

I was given Vyvanse because it supposedly gets absorbed in the intestines instead of the liver (like most meds) but I've heard arguments agreeing and disagreeing with this so I don't know if it's true or not.

Personally, I love my Vyvanse and can't stop praising it.
