Creatine, Concerta, and sleep

I'm trying to gain weight and I have started using protein shakes every other day, at night after work. I consider work to be exercise, since it involves a lot of heavy lifting and moving around constantly. I take a stack of the following before work:

1x36mg Concerta

1x150mg magnesium citrate

1x50mg zinc citrate

1x125mg l-theanine

2x400mg Lion's Mane capsules with food

After work, I try me best to eat a lot and rest. I have thought about adding creatine to my protein shakes but am questioning it's interaction with Concerta as well as how it affects sleep, and if it's worth it if I'm only active when I'm at my full time job. Note that I work night and wake up at noon.

Thanks.
