Hi All

I started on Vyvanse 20mg 3 weeks ago and I have had a reasonable effect from it. I expect to go up to 30mg next week.

My question is this:
I find that it takes 2 hours to kick in, then I have a good effect for about 5 hours then a dip for about an hour and a half. Then I have a reasonable effect again for another hour or so.

Is this dip normal?

I am ensuring I am hydrating and eating
