Runny nose

Help! Nothing stops the faucet that my nose becomes while on Vyvanse. I’ve been dealing with this from the get-go, and it’s getting so embarrassing at this point.

Not Benadryl, at least. I’m not sick, it’s not allergies, I don’t use illicit drugs, it’s the Vyvanse. I know I’m not alone experiencing this side effect; has anyone one found a solution? Or at least, a snot reduction.
