Thanks for the replies, although they were a bit late. My heart rate way fine and I felt fine on both, I ended up taking 40mg Adderall XR and 50mg Vyvanse, over the course of 8ish hours. I had some Xanax to calm the paranoia and take the edginess off of everything. I've done this once before and had a burning sensation within my chest the day after, but I think it was unrelated. Most likely heartburn or the lack of benzos that time (I have anxiety).
Everything turned out fine, even after going to a concert that involved lots of physical activity, only problem is it's 6, and I have to get up at 9, and I'm still not tired... Also threw in some 20ish mg of MXE later on into the night/morning, which turned out to have little to no effect on me... Strange...
Anyways, thanks for the replies everyone.
