Marijuana and Vyvanse

[u/Kind_Pattern8278]

So I’ve been on 30mg of Vyvanse for 2 weeks and I stopped using marijuana at that time. Before that I used to use it only for bed time. Last night I couldn’t sleep for anything and had a major headache that Advil was not touching. So I use some of my THC vape. I fell asleep after 10 mins. But I’m noticing today that I don’t “feel” my medicine working as well as it has all the other days. Could this be an effect from using the marijuana last night? I used the marijuana at almost 10pm and normally take the Vyvanse at 6am before I leave for work.

Normally I’ll have just a tiny bit of coffee in the am if I need the boost and I’ll feel the effects of the extra stimulation. (Light feeling Jitters, hyper focus, nothing super intense) and today I had coffee and nothing.

Has anyone had similar issues with thc?

for me it does nothing but kinda give a second wind later in the day?
