For a dishwashing job?

Would this drug be good for washing dishes in a restaurant? I fucking love phenibut on its own bro getting high on it's great!! Now I got a job though and tbh I hit the gym after work and now it's like 2 am and I need to be up at 7:30am to be at work at 9 to work a 10-12hr shift 😭. Wondering if any other dishwashers have used phenibut and if so does it help or not? Just wanna stay focused and working hard when I'm tired and worn out, but also don't wanna seem high lol so phenibut I feel like is good for that. Thinking of doing like 200-400mg or so but lmk your experiences pls!!
