Hi, I am 16 years old and I recently got prescribed 60mg vyvanse. This morning I ate a big breakfast, half of a subway sandwich and a few pieces of a pancake to be exact. I took my medicine after, I had a really good day. Paying attention and not having any headaches like I use to get. I also ate a chicken sandwich around lunchtime and pineapple. Around 6 o clock my stomach started to hurt so bad, I had the worst headache, and when I got up it felt like I was gonna throw up. I took some medicine for the headache, and I don't have a head ache anymore But I still have this awful stomach pain and feeling like I'm gonna throw up. And I notice I take really deep breathes.
