I started off with a false understanding of my meds, and now I can’t undo it.

okay, so long story short (kind of) i was diagnosed with ADHD about a year ago in my 30’s. i was started on vyvanse. I was on the freaking moon the first few days. I got so much done around the house, my mind was clear, i didn’t hear every fucking sound in the house all at once, it was a miracle. well my doctor didn’t tell me and i was not aware that the euphoric feeling along side of that would fade. so for the last 5 months ive been telling my doctor that it’s not working. i had mistaken that initial euphoria for the way the meds work, and believed they quit working when the feeling went away. ive since began taking more in hopes the feeling would hit and then i would feel like doing all of the things i need to do (im a SAHM and got a lot of my shoulders) and have the overwhelming motivation to do them. of course nothing changes but me running out early and having to go a week or so without them. it’s all just a big mess and im sure this is all over the place. what I am asking is if you all believe it’s possible to change my relationship with these meds. if so, how do i switch to the understanding that this is the way it is? I want to keep taking them. i can finally have conversations and i remember shit. i just don’t know how to stop chasing that euphoria.
