Managing Relaxation While Medicated

To be brief, I just went back on stimulant medication after being off of it for at least 6 years.

I'm reaping all the benefits I remember from before, but I'm also struggling a bit more with anxiety and just a feeling of tension.

I think I'm trying to catch up on all the things I was falling behind on, which is needed, but I think I'm pushing too hard and headed for more anxiety and burnout.

I feel like I need to work in some controlled downtime throughout my day. Somehow making it a task that needs to be done, but is also still relaxing.

Has anyone else struggled with this, and do you have any tips?
