I've been taking vyvanse for about a year & quarter, it has worked. But today things changed, recently I've been taking 40mg with 30mg pills(splitting one into thirds and taking a third with a full one) and it worked, my doc gave me the full 40 and yesterday it worked, I think, but today it seems less effective, if not making my add worse, I can't do any work at all. I haven't changed my diet at all l, I've been on 40 before and it worked. Could the vyvanse have stopped working?

You mentioned you've tried 40mg before and it worked, maybe it could have been a different generic brand? Sometimes that can make a huge difference.
Hey, I was on Vyvanse for about 2.5 years and noticed the same thing once in a while (maybe once a month). I thought my body may have been developing an immunity to the drug. I was prescribed 70mg. To counter the weird "off" days, I wouldn't take it on the weekends, and that kept my tolerance to it at bay.
Best of luck :O)
