Yep, when you have life with a major block and then experience a significant reduction in it you will definitely feel the pull to have even less. There is a sweet spot for meds and it can be different than you initially think.

I find that having my morning dose of 40mg Ritalin LA and my afternoon dose of 20mg Ritalin standard release works really well, but if I am just doing stuff like dinner and hanging out I may actually split that 20mg dose into two sequential 10mg doses a couple of hours apart. That gives me relief from some of the sensory issues for much more time but doesn't give me as much help with the motivation and activity level stuff.

So for you it may be worth considering an adjunct of lower dose Ritalin for after the big dose wears off, obviously depending on how it worka for you. I would recommend speaking to your prescribing doctor about trying a few different dose schedules for their recommendations, and really to use the language of testing so they understand you mean to experiment within safe bounds to understand how it works best. That means the same overall dose but tweaking the delivery timing and measuring the outcome.

Some psychiatrists will be uncomfortable with this. Some may be reluctant to have you try things and experiment. Some may think you are heading towards abuse. For that reason I would also recommend saying you want to optimise the dose you currently have, not increase, and also be open to other things like modafinil or similar non-stimulant meds.

Also, consider non-medication interventions. A great one is hard, heavy exercise, for example powerlifting. You burn a bunch of calories in a short time and release some of the body tension that builds over time and eventually causes issues. I find that lifting heavy things helps settle me and makes the next 3-5 days way better. Cardio never does the same for me, but maybe it would work for you.
