I tried methylphenidate after my diagnosis in 2021. It helped somewhat but I didn't enjoy the side effects - just a bit more high strung and anxious, even snappy or irritable. It had tradeoffs but ultimately the side effects were middling and the benefits were small to medium, so I stopped after a year. I tried lisdexamphetamine maybe last year and felt very similar so I stopped that much faster.
Right now though I am tempted to start again as work is so very busy and I'm really struggling. The issue is that when my remaining supplies run out I'm not engaged with the prescribers to get more.
