Vyvanse boosters that exceed the 70mg dosage I am on? I need a booster mid day and don't know if that is possible at my dose.

I have zero health concerns, blood pressure, appetite, or sleep issues with my meds. I have been on and off ADHD meds since 1995. I tolerate them almost too well. They immensely improve my quality of life, and since getting back on in 2020 I have gained a few promotions in my job going from grunt work to fabrication in a couple years plus some extra promotions. My meds are not very effective, if at all, about mid day now. I think this is that I am 260 lbs. of highly active muscle tissue, obviously not all of it is, lol, and I think I am metbaolizing the medicine much faster now.

Are boosters of 10 to 20mg a think on vyvanse?
