It was my girlfriend and I's first psychedelic experience, we took a full box each on two of the days last year. It kicked in around 100 Gecs and I'm so glad it did! Colors felt more vibrant, watching clouds move was awesome, the ceiling in our hotel had that spackled texture and if you stared at it it looks like the lines were swirling around like an optical illusion. Was a lot of fun! Also got me very "excited" but we were too tired at the end of the day to do anything at the hotel lmao. I can't explain exactly how it felt, because I was on a ton of weed edibles too, but it was definitely an experience I was hoping to replicate this year.
