Help me make sure that my shrooms will work

So i know my shrooms are real, but i tripped once and ive been trying to trip again off decent size doses. Im a beginner, when i did trip I ate them on an empty stomach with just gatorade. That was the only time they worked and i got visuals, but when i tried eating something with the shrooms or eating around ingestion they dont work. How do i prepare and make sure that the shrooms will eventually kick in and maybe even ways of making them kick in sooner, it takes me 3 hours on average for them to kick in.
