Can you mix gabapentin Vyvanse and Ambien?

That is pretty much my concoction minus Klonopin. I've found no interactions between the Lexapro and Vyvanse. Gabapentin, however, seems to lessen the benefits of Vyvanse, shortening its duration. The Klonopin, interestingly, has very little interaction with the Vyvanse but it helps with the crash.

My experience alone.
