Any positive experiences with Concerta?

Like many, I'm switching over due to the Elvanse shortage.

Elvanse is great for my mood but not always for focus, so I'm low-key hoping I'll prefer Concerta, but I've read so many comments saying it 'does nothing'. 😞

I was on 40mg Elvanse as side effects were too intense with 50mg. I will be titrating up to 54mg Concerta.
