How do I chill out on stimulants?

I have ADHD and I take Vyvanse and it helps with social stuff in the sense I can focus on what people are saying but it also makes me withdrawn and mentally tense. This could happen even without it but Vyvanse amplifies it, even if i go lower with the dose. Tried other stims and it's the same thing

How do I keep the focus without feeling like that? Any drug I can take to chill out? The easiest drugs I can get is RX clonazepam and DXM. I find l theanine relaxing too at 600mg but it doesn't last nearly long enough but maybe I could try megadosing?

What drug should I go with? As for benzos, I can keep my use in check, used clonazepam as needed in the past for years with no dependence or addiction but ideally if there's a safer drug for this I'm all for it as long as it gets the job done.
