Is vyvanse + weed a good combination?

I have a very low tolerance to both of them. I buy a little bit of weed maybe once a month, maybe even less. Vyvanse is still very new to me as I first did I 3-ish days ago. I generally do drugs quite rarely so a high tolerance is out of the question.

Is this combination enjoyable? If so how much vyvanse should I do? I’ve done 60mg as max but that just made me ask a bunch of questions. The two other times were 20mg each. That wasn’t anything special, apart from a late night walk.
